Re: Multi Material Tutorial

sry for the double posts but I have repeated the analysis with Netgen and it looks as if it is working with Netgen also.
(I think) this was not possible in .17, but it seems it is implemented now in .18.
It looks like Netgen does support multiple materials from now on *thumbs up* :D

Re: Multi Material Tutorial

I found a very important comment on the video I posted above. I translated this comment in English for all English-speaking people here (by google translate): With several materials with different E-modules, the stress evaluation at the contact surfaces is wrong! This is because in the FEM method, f...

Re: Multi Material Tutorial

I attached the .FCStd as well without the mesh for smaler file size Edit: BTW if you want the axle to go through the wheels, than you have to cut the axle out of the wheels. This should also work. In summary, it can be said that its important to: - have no overlapping geometries! - use compsolid ins...

Re: Multi Material Tutorial

You have to make a single mesh from all bodies combied in a compsolid. To do this select all bodies and make a boolean fragment and then switch from standard to compsolid under mode in the property of this boolean fragment. Than you can add a compound filter to remove the last compound and stay with...

Re: Topology optimization

Excuse me for the late reply I was very busy last month. Hello shlxx, well I think you are using precompiled version of FreeCAD 0.18 with Python3. In that FreeCAD-Version the module "commands" is not included. Additionally in FreeCAD 0.18 the API has changed a little bit, so that it wont run. This M...

Re: Flow simulation of two incompressible fluid streams

Thx for your feedback ! Just to be sure: The functionality of simulating miscible substances is not implemented in CFDOf yet, right ? I would have to deal with OPENFOAM directly. In case of imiscible substances how can I setup the case in Freecad / CfdOf ? I mean, I couldn't figure out where to cho...

Re: Error when installing cfmesh

Yes I get the same error when I try a manual build in the core terminal If you are running as administrator, then I don't know why there would be a permission problem. To build it manually, you can try running blueCFD-Core terminal from the start menu and type cd blueCFD/ofuser-of5 ./buildCfMeshOnBl...

Re: Error when installing cfmesh

It looks as though there is a permission issue writing to the blueCFD folder in Program Files. Try running FreeCAD as administrator (right-click on the icon and choose Run as Administrator) and re-try the installation, Hi Oliver, I have already tried "right-click" and "Run as Administrator" without...
