Error when running solver

[mikew]

Hello! I've just installed FreeCAD0.19, OpenFOAM8, Plot, CfdOF, dependency check is ok, all on Ubuntu 20.04LTS. Then, i've created a simple model for simulation of wind load on building, but there's an error when running the solver:

08:23:43 Start to write case to folder /home/user/Documentos/cfdofoutput

The problem seems to be with the Plot workbench dependency, but i've already reinstalled it and nothing changed. Any ideas of how to solve this problem?

For me your model runs without error.
BTW:
Define the house as a separate wall to compute forces with paraview.
Use the mesh-refinement option for the house, use bigger cells in the outer regions
(you use more than 5 mio cells...).
For a turbulent case, use cfmesh with boundary-layers at the house.

I get the same error as mikew.

Tested with simple test case and in addition downloaded hschrader model for testing.

I have seen the same thing with the Ubuntu 20.04 package. The AppImage worked ok for me, so I presume it is a packaging issue that needs to be investigated. I'd suggest using the AppImage for now.

Thanks! I've tried with AppImage, but then had some other new problems. Since I do not have much experience with Ubuntu, I've decided to run on Windows 10, and, after installing everything, it seems to work fine!

For me your model runs without error.

Thank you for the info! I was having trouble trying to use cfmesh, it always returned an error, but now (on Windows 10) it worked normally, so I'm gonna try the refinement as you suggested.

@thschrader do you realize you're running an older v0.19? Current is r22846, FYI

Updated FC and cfdof-wb.
Dependency-check gives "HiSA 1.2.1. required"
Installed HiSA 1.2.1., dependency-check ok. But when running the G7-test case,
openfoam gives error "solver Hisa not found". Reinstalled my previous HiSA 1.1.4,
dependency-check negativ, but solver runs (?).

Should be fixed

Installed HiSA 1.2.2, dependency-check ok, solver runs.
Thanks.
