Re: Progress of the general Computational Fluid Dynamics (CFD) workbench: CfdWorkbench

I agree with Worufu, but I have a problem to install both workbenches parallel due using same parameter in the installation path of preferences.

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Hi Oliver, please note attached file. I had to delete the meshing due to size. test.fcstd Result of this model, Keel and rudder are defined as hull, port and starboard side of hull, are placed in the default faces. here a summery of "createPatchDict" name hull; patchInfo { type wall; } con...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Hi Oliver, with the Cartesian mesher. But once again, not the mesher is the problem. The mesher is working excellent. In the file "createPatchDict" faces which were defined as i.e. "hull" were suddenly defined as "default Faces". And that is what I do not understand. In...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

by qingfeng.xia » Mon Jun 12, 2017 2:59 pm For near wall boundary layer refining, I once consider using GMSH, but I do not know how to reference the face by number in the solid (which seems exported as brep file). I stuck there without any progress. I disagree. The problem is not the meshing, that ...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

after testing and play around a little bit, I think there are some bugs: 1. as mentioned earlier not only the figures of fluid properties are not correctly shown, if edit the values again, also the figures of turbulence etc will change due to scaling and one has to be careful, not to miss the change...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Hi Oliver that was not your fault. I have read in a CfD forum, that cfMesh would be implemented in the new openfoam, but it is not. To install cfMesh to openfoam is .... tricky ... perhaps it would be a good idea to give users some comments how to do it. On my Linux computer I had minor problems, on...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Back from testing 1:1 fluid dynamics ;) I am impressed of what happened during one week. Of cause I tried to test it out, but cartesian meshing creates some problems. It is running, but without result. A failure message is showing: File "/home/peter/.FreeCAD/Mod/CfdFoam/_TaskPanelCfdMeshCart.py...

Re: Fork of CFD workbench

one step ahead ... after #raise in utility.py line 639 the program wrote the log file ideasUnvToFoam and in this file I could see, that boundary conditions failed and that this was the reason that openfoam stopped. Changing boundary conditions and everything was perfect. So ... I think the main prob...

Re: Fork of CFD workbench

regarding the crash reported yesterday: after trying to understand where the failure during writing the case files ocures, I have got now an Ubuntu message, stating that openfoam crashed with the error message: ideasUnvToFoam crashed with SIGABRT in Foam::error::abort I have tried now to stop the cr...

Re: Fork of CFD workbench

Hi Johann I know, that`s why I tried to work with the region, idea behind, to create a boundary layer and mesh this with a fine mesh, but this did not work at all. A better meshing system would be highly appreciate, of cause RANS, possibility to work with waves .... etc I know a lot of things what I...
