Diffraction , I left it, how it is.
For the unusual issues that comes in the image source component, so, is it something strange? But, I still have the same issues when I sets any integer component (single or multiple) in the “reflection order” of the image source component, in the “image source order” in the ray tracing component, and again, when I connect the output “Direct sound data” of Direct Sound component in the Energy Time Curve.
Do I wrong something with the integer component? I used it already in the first parts, for sets “grasshopper layers”, in the “Scene” component, but here it works. Should I start with a new file?
For the multi-object optimization, thank you for all suggestions. Yes, I red PHD thesis work of Tomas Mendez and the article “ EDT, C80 and G Driven Auditorium design” and still others. Thank you to all these articles, I decided where to focus my thesis.
I understand the potential of Multi-object optimization, and problems that I can finding without using it. Actually, in the beginning of my thesis, I tried to jet in contact with the Politecnico di Torino, but was not easy because I’m not a Politecnico student.
Here, in University of Florence (Building engineering), there isn’t a department or someone that is already familiar with these field of study, so, as you can image, for design my thesis, I can confide on online resources. So far, my Professor suggest me to begin with a Nonlinear Global optimization like Galapagos, and only after see the multi-object. In this way, step by step if something doesn’t work is easier to understand way and where something is going wrong: if are problems due to the setting of the programs, because we are not practical about these, or if there is a wrong in the simulations or in the algorithm and ect.
Do you think is a good way for go on?
Thank you very much,
Kind Regards
Giulia

To be more precise, I'm not quite clear how to apply this equation to the helicoid and integrate it into my code:
where corresponds to a helicoid and to a catenoid.
I've made some attempts not worth to be shown here. Maybe somebody can help me with a pseudocode or a simple description how to start solving this classic geometric transformation.
Thanks, Sebastian

e and i get it. If you have time check the attached papers we published a while ago in relation to the contribution of thermal mass in the reduction of temperature in residential buildings. See the nice contribution of the heavy TM or the lower one for light TM.
As for the solarHeatCapacity, your description (of the 50W) is derived on a 1 Facade/Floor ratio and fully glazed. The only way to reduce it is to increase the ratio (bigger facade area). Which is not recommended (energy losses), but this is a different issue. So, roughly, we can say that 50 is the lower value. If i have less glazing area this number will be higher (right?)
I want to define a value list of "architectural situations", so it is easy to explain and understand. One situation can be:
"Ratio facade/floor 1 & Fully glazed" = 50
"Ratio facade/floor 1 & Half glazed" = 75
"Ratio facade/floor 1.5 & Fully glazed" = 30
"Ratio facade/floor 1.5 & Half glazed" = 50
"Ratio facade/floor 0.75 & Fully glazed" = 70
"Ratio facade/floor 0.75 & Half glazed" = 90
Makes sense for you something like this?
I also defined a value list for the timeConstant like this:
Light Building (Mobile home) = 1Medium-light building (Cement tiles on floor) = 4Semi Heavy Building (Concrete floor + Tiles) = 8Heavy Building (Concrete floors/ceilings + Heavy external and internal walls) = 12
As for the first 5-10 cm effective TM in general my assumption is that you take half of the mass to your space and half to the space above/below you. Will be interesting to do a parametric study on just the thermal mass, uninsulated and insulated to see what the depth limits effectivity will be. Interested in doing such a study together? Can be a nice work even for publishing.
Thanks a lot ... again,

In this case we see a geometrically approach, which doesn’t works efficient, because it required knowing how they behaviors together before, and I think it is not the ‘really behaves’.
To make the structure ‘really behaves’ I tried use kangaroo and the result works very well! As you can see I simply give the 2-set reverse UForce, and then they start to rotate until they found their equilibrium. That means 90 degree rotation. I was wondering what we can do to make a endless-rotation. I am mean 360 degree or more like this:
https://www.youtube.com/watch?v=4owFczeqqMQ
By the way, I try to give supports which allow a horizontal movement only (Just curious how we could keep the anchor-movement horizontally and in the same layer, for example like usual supports for compression ring…). I use the AnchorXYZ, but Kangaroo-Engine seems don’t accept its output.
So maybe some one knows a better solution?

problem later) to fit more shapes that are otherwise won't fit in.
On the example below horizontal rectangle couldn't fit in but its rotated analog could and thus was placed in.
Later, when placed shapes are used to generate frames, because of this rotation, the position of the starting points changes and because of the approach I use to generate the frames some angle values are attached to the wrong corners, this brakes the frame shape and looks like this (on the left the frame of sick shape and on the right the frame of the healthy shape):
Again, this happens because the angle values are assigned to the specific corners (points) and previously rotated shapes get these all messed up:
Easy fix, don't rotate the shapes, problem is, I've already baked a good number of them for later use. I'd like to avoid regeneration because it takes a lot of time and without rotation I constrict the algorithm even more.
Better fix, use a different approach, this is where I'd like to hear suggestions and kicks in a right direction. Please take a look at my definition. It works but I have a feeling like giving an amputee a job of sweeping the floor.

Human UI
Primary Development by:
Lead Developer: Andrew Heumann / andheum / @andrewheumann
Product Manager: Marc Syp / marcsyp / @mpsyp
Contributing Developer: Nate Holland / nateholland / @_NateHolland
Gone are the days of faking a user interface by laying out sliders and text panels and hiding wires on the Grasshopper canvas. Human UI interfaces are entirely separate from the Grasshopper canvas and leverage the power of Windows Presentation Foundation (WPF), a graphical subsystem for rendering user interfaces in the Windows environment.
OLD NEW
In other words: Human UI makes your GH definition feel like a Windows app. Create tabbed views, dynamic sliders, pulldown menus, checkboxes, and even 3D viewports and web browsers that look great and make sense to anyone--including designers and clients with no understanding of Grasshopper.
Human UI has been in development at NBBJ for over a year, as part of a larger NBBJ Design Computation initiative to deliver our tools internally as Products -- with fully automated installation, managed dependencies, analytics, documentation, and “magical” user experience. Human UI has been a huge component of the user experience part of this puzzle, and we are excited to share it with the larger Grasshopper community so that others can benefit from it and contribute to its development.
The initial release of Human UI is accompanied by a few simple examples to get you started, but we have developed sophisticated user interfaces with these tools at NBBJ and will slowly be rolling out more advanced examples. We also look forward to opening up the development to the community and seeing what new features and paradigms we can add.
Download the plugin at Food4Rhino and get started building Custom UIs for Grasshopper right away! We are happy to answer any questions or field discussion in the dedicated Grasshopper Group. Please join us!

hopper no requiere de conocimientos de programación o scripting para permitir al diseñador trabajar de forma generativa y paramétrica. No son necesarios conocimientos previos de Grasshopper pero sí de Rhino a nivel básico.
Controlmad es Centro Formador Autorizado Rhinoceros y Rhino fab Studio.
Nuestros profesores son Instructores Autorizados Rhinoceros con experiencia universitaria, nacional e internacional.
El curso y los ejercicios a desarrollar están enfocados a diseñadores, arquitectos, ingenieros y estudiantes.
En este curso introductorio el alumno se familiarizará con términos básicos de la estructura de Grasshopper, como “listas de datos”, “dominios”, “estructuras en árbol”, etc.
Es un curso de 18 horas, con el que se pretende entrar en la lógica de trabajo de Grasshopper mediante diversos ejercicios, de forma que el alumno sea capaz posteriormente de desarrollar sus propias gramáticas, con la confianza que da comprender los términos básicos de programación sobre los que se apoya todo el sistema de trabajo de Grasshopper.Para este curso no son necesarios conocimientos previos de Grasshopper, pero sí de Rhino (a nivel básico).
También se vincula el programa con la impresión 3D aprendiendo a exportar archivos desde Grasshopper con los requisitos mínimos de impresión 3D. Se realizará una demo de impresión en el aula.
El primer día del curso se le facilita al alumno un manual-tutorial con los ejercicios a realizar, en PDF.
A la finalización del curso, y siempre que el alumno haya asistido al 80% de las clases, se le otorgará un diploma oficial acreditativo del curso.

creating the structural frame, finding the endpoints, linking these endpoints with curves and afterwards lofting the surfaces between the curves.
The results were quite nice, however, the procedure is very time consuming and inefficient. There is just too much copy-pasting involved.
(see attached file: "Old Attempts.zip" )
Mesh relaxation:
I have later on used Daniel Piker's tutorials on Mesh Relaxation and realized that this might be the way to go.
The link to these online tutorials on wewanttolearn.net is:
https://wewanttolearn.wordpress.com/2011/10/22/mesh-relaxation-kangaroo-tutorial/
His tutorials, however, only deal with mesh boxes which are ideal cubes. He then joins them together in various directions, but it is under 90 degrees angle.
( see attached file: "Daniel Pikers Examples" )
What I would like to achieve:
I want my bridges to go in all directions and angles, not just under 90 degree angle.
Ideally I would like to make a square (polygon) follow a curve (which moves in all axis) at certain number of division points. I would then loft these squares into a mesh and use that shape as a mesh box. I would later use this mesh box and relax it the same way as Daniel Piker used the cubes in his tutorial. The anchor points are only the vertices of the squares which create the lofted mesh box.
( see attached file: "New Attempts" )
As you can see below this procedure works even if the curve is moving in all directions not only along xy axis. There are, however, many problems connected to it.
The problem:
Despite all the effort I cannot seem to come up with a design where I would be able to draw a random curve which would be the guideline for my mesh box and then apply this box to one definition in order to relax the mesh and create the shape that I want. Without this I am again forced into a lot of copy pasting as the final mesh box is made out of several sections.
Also is there any way I could make the final resulting mesh a bit smoother? Increasing the number of mesh faces is probably the only way, right?
Thank you guys so much for any potential help.
All best,
Luka

of a hack to push it to an android device, and you can't use labels, which is a very bad point!

I won't buy an Iphone!
The other is Control OSC. It looks rougher, but it has a lot of advantages to me.
+ Game of Life included!
+ you can use and update labels :))
+ Has a nice muti touch widget unfeatured in touch osc
+ You can script the interface using java script manipulation in gh, stream it to your dropbox and update in one "tap", as follows
Does anyone have experience with scripting interfaces for this software? I'm stuck already. I know nothing of java script to begin with. As you can see I managed to format the labels but the osc message I could not find a way, it stays untouched.
Just in case someone knows better, here are my "objects" (I said that right?). The userXXX are replaced in GH.
