Re: Adding boundaries in FC 0.17 installed in Ubuntu 17.x

Dear All I appreciate your fine jobs in here. I am running FC 0.17 in Ubuntu 17.x. But when I clicked Boundary icon, it shows something irrelevant. What should I do? Thanks. Bugae That shouldn't happen. Please could you follow the steps in the post at https://forum.freecadweb.org/viewtopic.php?f=37...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Hi Thomas I think I have managed now the problem to show the water surface including waves. The problem seems to be the meshing of the water surface. If you only use the initialisation zone you are defining with 1/0 the box for water, but that it. I defined now 2 zones, one atmosphere and one water...

Re: meshing problem

Hi All, I have just installed the cfdof module in freecad to start some trials and I have come up with 1 semi major issue and 1 major issue. 1st) when I create a volume (a rectangular section which is 40mmx40mmx2500mm) in part design and create the container for open foam and try to mesh the volume...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Hi Oliver, Yet again I'm very impressed and grateful for your efforts and support. After checking the boundary naming I realised that I had used a space in four boundary names, eg, "Input 1". I removed all the spaces and it has worked fine now. Bloody marvellous, as we say here in England :lol: Che...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Okay Thomas, thanks again and all agreed with your suggestions. I now realise that I must re-mesh before running the iterations, so yet another learning step. Thank you again. Now please tell to "give up" (to put it politely) if I'm being a pain but I had a thought of ensuring I had things understo...

Re: 2d flow over 1d object

I played a bit with the number of boundary-layer-elements / first-cell-height parameters and found a working combination. To me it seems this sometimes works and sometimes not. with the boundary-layers the velocity-distribution at the wall looks good: Bildschirmfoto von 2019-01-28 13-16-29.png If y...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Okay, now the strange bit again. As you will have seen when I used your new corrected case Thomas it worked great and I started the Paraview tutorial excited. However, I came back to it today and I'm getting the same failure again: Did you restart your computer in between writing the mesh and tryin...
