Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Thanks Oliver. Yes, I have installed blueCFD but I now see that I do not have OpenForum install directory stated in CFD Preferences . I thought BlueCFD set this location. I've stated to download and install blueCFD again so hope this will sort it out. What should the OpenFOAM install directory be? ...

Re: Stone arch FEM

Hi, has anyone tried modelling a stone arch in FEM? This is hard stuff with FEM alone. I think you need graphic statics too. Some inspiration: https://www.block.arch.ethz.ch/brg/ http://spaetgotische-gewoelbe.eu/entwurf-spaetgotischer-gewoelbe/ http://block.arch.ethz.ch/eq/files/SD_VI_L-05_15238871...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

for me it works, please see model. Could you please confirm you're using the old workbench, i.e. pre 27th June 2019 when there was a significant code change? I believe @CrossleyUK is using the new one and so am I, so I'll take your settings to see if I can get the new one to work the same. Confirme...

Re: CFDOF nicht newtonsche inkompressible Medien

Hi, die Definition nicht-newtonscher Fluide geht mit der cfdof-GUI nicht. Du kannst nur nachträglich die case-files überschreiben und dann den Rechenlauf abschicken. Hab ich aber noch nicht ausprobiert. Eine ähnliche Diskussion wurde hier geführt: https://forum.freecadweb.org/viewtopic.php?f=13&t=21...

Re: Punktanzahl eines mesh verkleinern

Hi Bernd,
nur aus Neugier:
Wie ist das Geländemodell ursprünglich zustande gekommen?
Laserscan? Dann Punktwolke in Allplan importiert?

Re: structural pipes

Fuse 2 or more cylinders, use the "facebinder"-tool in arch-wb
to extract a 2D-shell. With the "ElementGeometry2D" you can define
the shell thickness.

Re: FEM-Fehlermeldung Gmsh

wenn es sich um die Fehlermeldung "unknown element typ for unv export ... " handelt, die hab ich bisher stillschweigend ignoriert. Ich sollte dem wohl mal nachgehen, wo das herkommt, und ob es eine mögichkeit gibt dies zu umgehen. Es wäre interessant zu wissen, welche GMSH und FreeCAD version ihr v...
