he TOF and TSRF indices. They show, how "distant" is your _PV_SWHsurface from the optimal _PV_SWHsurface surface in terms of tilt and azimuth angles.However, in your case we are not interested in TOF and TSRF indices. We would just like to know what are the _PV_SWHsurface optimal tilt and azimuth angles, regardless of the supplied _PV_SWHsurface.
So the circular surface supplied to the "TOF" component's _PV_SWHsurface input is irrelevant. It can be of any area, and any tilt/azimuth angle.The PV_SWHsurfacesArea output of the "PV SWH system size" component depends on a couple of factors:moduleActiveAreaPercent_ (leave it at 90%).
moduleEfficiency_,
systemSize_.Calculation of systemSize_ depends on your electricity demand, cost of the PV system, type of the object, country, local regulations etc. This is something that an engineer needs to determine.For example, in USA for a residential house in the Sunbelt, depending on finances, a household would try to cover 100% of its annual electricity needs with their PV system. Which means that the systemSize_ you chose needs to cover the annual electricity consumption. You can perform EnergyPlus simulation or use any other way to get the annual electricity consumption.
Ladybug "Photovoltaics Performance" component can calculate the optimal systemSize_ by given the annual electricity consumption.However the component is made to address fixed tilt and azimuth PV systems only.An approximate way to overcome this is to calculate the optimal systemSize_ for fixed tilt and azimuth PV system, and then multiply it with the "difference in %s" panel at the very right of the fixed_vs_tracker_PV2.gh file. Again, this is not what Ladybug "Photovoltaics Performance" component is made to do, but it will probably get you in a ball park.
Inputted 32 degrees for north_ direction is actually 328 degrees.This is due to Ladybug Photovoltaics being based on NREL model which uses clockwise angles convention. This convention is also most commonly used in solar radiation analysis.

orward polygon modelling combined with a subdivision surface method to smooth the modelled polygon control cage (see this andthis).
The Weaver Bird plug-in has several methods for subdividing and smoothing a mesh including the probably best known method Catmull-Clark as well as laplacian smoothing.
Although Grasshopper is becoming better at handling mesh construction and modelling you might want to consider packages such as 3ds Max, Maya, Modo or Blender for doing the initial cage (they all have most of the standard tools one would except from a polygon modeller). For Rhino there is also the funky fusion between subdivision surfaces and NURBS called T-Splines (gave it a spin a few weeks back, has some pretty decent polygon modelling tools actually).…
s random reduced with the random reduce component.
Then the random reduced surfaces, is extruded in z direction with negative factor, The plane surface is also extruded in z direction with negative factor, then i used Trim solid, and had about 40 boxes cut in the xy plane with different hight.( hight is from the flowing surface)
The i open a new grasshopper file, and take brep container, and get one of the boxes cut in xy plane, but if i use isotrim on the brep faces or subdivede quad from lunchbox, the divide component show orginal extruded surface and not the smaller one i got after using Trim solid, on the extrusion.
is it clear or you need the file, and have anyone a answer
thank you

orders from bottom to top. There are three pre-set heights: 20,000 / 50,000 / 80,000 (or 20, 50, 80 meters, I'm working in mm).
So if the three cantilevering volumes would be numbered 0,1 and 2, then I'm looking for a way to let Grasshopper generate the following:
A = 20m-position
B = 50m-position
C = 80m-position
(A,B,C):
0,1,2
0,2,1
1,0,2
1,2,0
2,0,1
2,1,0
Attached is wat I have so far, I have only managed to make simple translations per geometry.

summer because of the relative humidity of outdoor air will be over 80%.
I want to set the schedule like this
1) cooling setpoint to be 27C degree and max humidity to be 50%.
2) when the outdoor air temperature is lower than 27C, open the windows and ventilation naturally.
3) Air conditioning and dehumidification are needed only when the occupancies are at home (almost at night) and Natural ventilation is not to be.
4) Accept the indoor air relative humidity to be almost 100% when dry bulb temperature is lower than 27C.
Now, I set the air conditioning schedule as cooling setpoint schedule, but there are no components to set a dehumidification setpoint schedule.
The dehumidifier keeps working all day whichever the windows are opening or not.
How can I stop the dehumidifier during the windows open?
thank you.…

angel but when it comes to material behavior, stresses, surface tension i think that "our" tools are still no complex and powerful enough - and like i said i didn't really see the benefit in the work of my friend form the digital experiment.
so i think the question is is there a benefit from your digital experiment or do you rather stick to the physical experiment.

of 400 interlocked rings in a 20 X 20 grid.
V1 - A single 'suLoop' component doing 400 'SUnion' operations (20 X 20): 11.6 minutes
V2 - Two phases: 5 X 10 in phase one and 2 X 4 in phase 2, 58 'SUnions' total: ~88 seconds combined
V3 - Two phases: 4 X 5 in phase one and 4 X 5 in phase 2, 40 'SUnions' total: ~104 seconds combined
Again, these Profiler benchmarks don't reflect the whole picture, and might be affected by other things I was doing on the laptop while the code was running.…

,
and then I saw under Application that resources are managed by 'Icon and manifest'.
That can also be set as 'Resource file', but then a file path is required.
Is 'Icon and manifest' OK, or have I to set thing differently ?
Also, in the class code I inserted the following:
( I saw it mentioned here in the forum )
protected override Bitmap Icon { get { return Resources.colour; } }
( colour.png is the image file's name )
but VS gives me an error, saying:
Error 1 The name 'Resources' does not exist in the current context C:\Program Files\Rhinoceros 5 Evaluation\gh\plug-ins\ColourRhOb\Class1.cs 88 26 ColourRhOb
Did I miss a reference in the code ? Here they are:
using System;using System.Drawing;using System.Collections.Generic;using Grasshopper.Kernel;using Grasshopper.Kernel.Types;using Rhino;using Rhino.DocObjects;using Rhino.Geometry;
What am I doing wrong ?
Thanks
