Simple wind analysis Eddy3d

trumori · June 20, 2020, 9:25pm

Hello everybody

I am trying to run a wind analysis with the simple wind analysis template from Eddy 3d.
Unfortunately it does not work. When I press the bottom to run the analysis nothing happen.
Anyone have any suggestion why the definition is not running properly?
I attached below my definition.
simple wind analysis.gh (32.8 KB)

Thanks in advance

I manage to make some progress within the grasshopper definition after installing OpenFOAM.
The issue now seams to be related with the pedestrian comfort component and MRT component which are giving me some errors.
I am attaching here the definition.
Does anybody have any possible solution?
Thanks

Hi Tiziano,

I, unfortunately, can’t see which particular errors you seem to get, hence I can’t help out.
Please make sure everything is installed according to what is mentioned (the folders need to be identical!) here.
Please also make sure that you are aware of the limitations of the experimental components (especially MRT). You’ll find some basic information in the description of the component, more detailed information is available in the papers linked on the website.

Best,

Patrick

HI @trumori. Did you manage to make it work, the MRT component?

Hi asisintel

Unfortunately I did now manage to make it works.
Do you have the same problem?

Yes @trumori have the same issue. I installed radiance in Drive C as instructed but When MRT component is toggled rhino crashes

Hi,

First thank you for the awesome job! @eddy3d
When I’ve done 3. Mesh & Simulation, it went well and i could see the result from rhino.
but when i turned on the Visualize Probes, it doesn’t work any more…

i saw in previous discussion, you recommand paraview, but when i turned on the paraview, it warned me like below…

ERROR: In C:\bbd\2d618e80\build\superbuild\paraview\src\VTK\IO\Geometry\vtkOpenFOAMReader.cxx, line 7590

Hi Bjeun94,

Number of cells/points in mesh and field don’t match: mesh = 165462, field = 166077

mesh refers to your mesh and field refers to your simulation results, they both have a different number of cells. I think you ran some simulations, then remeshed your case with different settings afterwards which is why you can’t load it anymore into Paraview.
I suggest to start from the beginning and to check your mesh before you start the simulations. From there on, don’t touch the mesh anymore.

Best,

Patrick

I do encounter the same problem. The MRT component crashes GH and Rhino, and this happens on the Annul Wind Study template definition as generated with Eddy3d. I tested this on 2 separate PCs.

What could be causing this?
Thanks,
Andrea

Hello,

I am wondering if there has been any progress in attempting to run the MRT component without GH and Rhino crashing? Any insight would be much appreciated!

Thanks,
Nick
