Re: Fork of CFD workbench

[..]@developers: have you any suggestion for my parallel computation problem? General advice: 1. Check how the solver should be started to use multiple threads (command line switch?) 2. Test manually outside of FreeCAD - does it work? 3. Check how the solver is started from FreeCAD - is the switch ...

Re: Tolleranza Cordale

Se stai usando la versione di sviluppo (0.17) non trovi più le impostazioni di tassellamento su preferenze. Ti consiglio usare il workbench mesh, selezionare la parte che vuoi esportare, barra programma -> Mesh -> Crea Mesh da una forma, usa la tassellazione standard e imposta la deviazione, di nuov...

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 pro...

Re: Fork of CFD workbench

Amazing work! It works very well, it was time I'm searching of something like this, simple to set, easy to process and full open also for Windows. Congratulations again. I try some test with wing simulation, it works good, but the parallel core feature doesn't work. Case writes data, Solver starts t...

Re: Calculation done but no results

Solved! The problem was in the mesh defintion "Create a Fem mesh node set". If the parameters (translated from italian version) "n° of segments by edge" and "Number of segments by radius" are set to 1, calculix crashes everytime. Obviously the mesh definition can be set to "user defined". Thanks to ...

Re: Calculation done but no results

However I can't understand if there is a problem in the file permission, when writing *.inp, or in the mesh definition. This looks like the error when Poisson Ratio = 0. Are you using the "None" material? Not, I set steel material. But I can't verify if it is written in the right way in *.inp, I ca...

Re: Calculation done but no results

Oh, thank you so much. I read carefully the log and there was an error (process crashed), I was confused about the end sentence "loading result...". I checked the new working directory but it remains empty, also if click the button "write *.inp file". If I click "Modify *.inp file", freecads open it...

[Solved] Calculation done but no results

Hi, I have a problem with FEM module, it is not clearly reproducible, it happens with huge number of tetrahedrons (>200k) or in re-modified parts. Calculix works during the simulation, but I cannot see the results; the result icon remains gray and the files in fem folder are all setted at 0kb, with ...
