izes like 0.6m, 0.8m, 0.9m and 1.2m are the most "common": In cases where mechanical floors are a must (hospitals for instance) a 2.4/2.4 is quite handy (habitable/mechanical per floor). You can try 1.8/2.7 as well (floor/habitable) since 1.8 floor thickness can host HVAC and some decent W truss size. Also 1.6/2.4 (floor/habitable) is used in small buildings. NOTE: see next.
3. Don't forget to include corrugated metal height + concrete screed height + raised floors height: for the latter, say, something like 0.3m (modules + adjustable mounts + free space for electric stuff [boxes etc]).

ybee_EnergyPlus Window Shade Generator" component.
3. SolveAdj component has the input to set BC for interior surfaces.
If you want to set them to adiabatic then you can use setToAdiabatic components.
4. For natural ventilation Chris has provided extensive answers including this one.
If the component doesn't work then you need to download the files manually from github and replace the userObjects with the old ones. You have to do it separately for Ladybug and Honeybee which can be painful. Is there anyway to change the firewall settings?

till quite rough.
I went through your attached log but it seems to be a successful run, perhaps the error log wasn't attached. In any case, I believe we have identified this issue. The goal of the update fvSchemes component was to apply schemes to finalized meshes in an automatic way. While this is useful for new users it is also a dangerous thing to do in CFD studies.
The component works by relating mesh quality to the mesh non-orthogonality, which the checkMesh component reports. While non-orthogonality is one of the important criteria of mesh quality it does present difficulties on some kind of meshes, especially like the simple cases that BF has been meshing so far.
The example case of simple box buildings in a wind tunnel above for instance will appear as a good quality case for even the lowest of cell-count meshes, simply because it is an orthogonal geometry. That means that checkMesh will probably report low values (imagine an empty blockMesh of 10m blocks has a non-orthogonality of 0) which in turn means that higher order schemes might be paired with actually low quality meshes. This I believe is causing problems.
I posted a possible solution to this here https://github.com/mostaphaRoudsari/Butterfly/issues/57. The idea is that Buttefly provides additional options to the users, enabling them to choose between first-order (faster, more robust, but lower quality schemes) and second-order (slower, less robust, but more accurate) schemes depending on mesh quality, stage of assessment, etc. In cases like the above mesh quality a first-order scheme might provide a better option. To test this I am attaching an fvSchemes file you can use by replacing yours in the /system folder of the case.
As a note however, I would like to stress there is so much that a tool like Butterfly can provide in this area. Meshing is a quite complicated and demanding part of the process, involving a lot of trial and error. Sometimes the problem is just the mesh and not the solution options (GIGO stands true in CFD as well). It does however get easier with experience. The safe advice is the simplest one: when changing solution options doesn't help, refine mesh and run again.
Kind regards,

Hi friends,
trying to get a cumulative sky image metric to run and encountered an issue with the image-based metrics component. It throws:
Runtime error (KeyNotFoundException): honeybee_materialLib Traceback: line 768, in main, "<string>" line 1442, in script
I guess this is some sort of setup issue on my end, or I messed up the definition? Any help appreciated.
Thanks,
Max

rasshopper (only compatible with IRC5 controllers). I made some tests with kinect and phones and tablets and it works (so if you have a good position for your kinect you can already know when a user is too close to the robot and stop the execution or slow it), but due to controller limitations I am now working on a different way of sending and managing data to the robot to minimise the latency of the system.
Galapagos will not allow you to switch between configurations and toolpaths, since configurations are computed by the IK solver and managed by several informations in the code, that can only be overrided or changed depending on the interpolation you use (MoveJ/MoveL/MoveAbsJ etc.). And once again, some configurations are not reachable depending on the rotation domains of certain joints (4th one for example) or also because linear interpolations cannot work for targets necessiting more than 90° of rotation. HAL computes by default the most "accessible" configurations in order to minimize 4th axis flip (which is a pain), and the next update will have a fix to allow to count the laps you do with the joints allowing more than 360° of rotation in order to prevent to reach the max values (otherwise the robot is locked and the application is stopped), there is a little bug on the 6th axis on the current version. IMHO these questions are much more important to solve for the design of your application than the approximaton of the workspace (it is very easy to measure the max radius of rotation, and singularities can always been reached using moveAbsJ).
By the way, all those things are not exactly trivial to solve (some are with the new verson of HAL, but not all of them), so depending on how far you need to go, I hope you don't have a deadline soon...…
eople use different methods and components was the way that I learnt most of what I know (and it might solve parts of other's problems)! It's always apparent from forum posts that everything is work in progress.
The "divide curve" components gives you tangents (T) to the curve at the points you've made. You want the perpendicular (right angle) to the curve, so need to rotate this vector around point on the curve (P) by 90 degrees or Pi/2 Radians .
It seems you're finding your lengths as required, but then passing them through a unit Y vector - so they are only ever going to move in the Y direction. You need to use an "Amplitude" component with the perpendicular vectors from above and the lengths you've calculated.
Before sweeping you'll need to properly align the rectangles such that they are also perpendicular to the curve.

se the final panels that you want to rotate, or is this file just an example? Do you also have panels in other facades (in other planes)? Is the positioning of the panels random? Is it completely random, or are there some rules? Are the dimensions of the panels fixed or can they change, and how?
2. If I understand correctly, you want to have 2 different rotations, right?
2a. The first rotation is around the edge of the panel that lies on the facade and you want it to be between 0 and 90 degrees, right? How is the angle for each panel defined? Based on the sun's beams direction and, if yes, how exactly?
2b. The second rotation is around the X axis, on the right point of each panel (which is fixed on the facade) and you want the angle of rotation to be specified based on an attractor point, right? Is there a minimum and maximum angle or do the panels always align with the attractor point?
For a better understanding of these questions, see the attached definition (open it together with your 3dm file). Here the first rotation is the same for all panels and is controlled by a slider (until you explain how you want to define the angles). The second rotation doesn't have any constrains, so the panels always "look" at the attractor. But, as you can expect, strange thing happen this way: Panels hit into each other, rotate until their solar side is looking downwards, etc.
Still, I believe, if you answer the above questions we will get somewhere.
Cheers,
Nikos…
