Re: Freecad läuft auf Desktop nicht

...und es läuft alles prima. Danke an alle. Gruß Bei mir leider nicht :( Die FC0.18/0.19 Versionen starten, aber die Grafik "springt" (z.B. beim drehen eines Körpers) Die FC0.17 "Roland"-Version (und ältere) hingegen läuft einwandfrei. Betriebssystem ist Win10 64 bit auf Intel Celeron E3300 CPU mit...

Re: parametric pipeline between freecad and openfoam

Ok, the compressible case is still not supported in the current version. :roll: I understood my mistake. ++remy Try to use the HISA solver at windspeed lower mach 0,2. This is windspeed on buildings. Report your results. Here. Greetings Thomas EDIT 18.05.2019: Here is an example using HISA-solver a...

How did you get the vertical distance scale overlays?
See picture, enable "Show Axis".
At the moment I use paraview 4.0, newer versions crash, I have problems
with my graphics driver. FC 0.18 and above crashing too, FC 0.17 Roland works.
No idea why...

Re: combined contact thermomechanical analysis

A screw joint with pretension is shown in this example: https://forum.freecadweb.org/viewtopic.php?f=24&t=31997&p=266772&hilit=pretension#p266772 It works without *PRETENSION card ;) Sorry, I couldnt remember the post ;) To "shorten" the bolt works fine. Prestressing a M20 bolt with 160 kN gives ap...

combined contact thermomechanical analysis

Hello, the controlling-engineer got me... ;) I must calculate a tube connection with flanges and prestressed bolts. (steel S235, all bolts M20 10.9, prestressing 160 kN each bolt) Running a contact analysis without prestressing works fine. When "cooling" the bolt (-180 K) to simulate prestressing, I...

Re: About strain and Stress

Dear FreeCAD FEM users, I try to use FreeCAD/Calculix and I really don't understand why there is no possibility to have the strain and stress tensor in the results. The Strain/Stress tensor are a symmetric second order tensor, they have 6 coordinates that are written in Mandel notations (Exx,Eyy,Ez...

Re: ArchSite Compass

I am with you, I do not know yet how to handle the world coordinate problem in FreeCAD. We have the same problem. We get terrain data from the geotechnicians in world coordinates. For sites in switzerland the global origin in FC is hundreds of kilometers away from the cad model. So we type the terr...
