@Raedchen_im_System, Thank you again for your tutorials that are possibly making it possible for this old dog to learn a new trick. (an English idiom--not sure if it translates) I was telling a coworker about this problem at work today. We wondered what the physical significance is of a finite plate...

I have been working on Tutorial 3. In it the presenter does an analytical calculation of the expected shear force on the moving plate just as I would have. But the results from CFDOF are something like 25 - 30 times the analytical solution. The presenter says this is expected, but doesn't say why or...

Hi Raedchen_im_System , Thank you very much for your answers. I ran your Tutorial #2 Updated and got varying results. Sometimes it yielded a residual curve very similar to the one in your video, but other times, the residuals oscillated, and never got down to 10E-4. Successively meshing and then run...

Dear Raedchen im System, I downloaded and ran your updated file. While the refinements were reversed from mine, the output looked almost the same. But when it ran, I noticed this: 20:12:53 Writing case to folder C:\Users\Paul\AppData\Local\Temp 20:12:53 Matching boundary conditions ... 20:12:54 Popu...

Hi Raedchen_im_System , Apologies for my bad form. Thank you for your patience, and I'll try to do better. I had already determined that there must be a change in the mesh refinement, and I made the refinement factor for the volume refinement = 0.250, and left the surface refinement at 0.5. The mesh...

Thank you for the tutorials. I have followed the first two, but the solutions I get are very different from the ones in the video. For example, in the first tutorial, my system takes more than 400 iterations for all the residuals to get below 1E-3, while yours converges to less than 1E-4 in less tha...

the last error message says it's looking for surfaceFeatureEdges.exe, and I see that file in the path it gives. I can't figure out what I'm doing wrong.

I had trouble installing CFDOF and its dependencies, but I think they are mostly there now. I can write the mesh case, and it looks like the mesher runs, but it exits with: 16:44:48 CharacteristicLengthMax: 5.0 16:44:48 Exporting mesh refinement data ... 16:44:48 Matching boundary patches 16:44:48 M...

I haven't been able to find the page you found to fix your problem. I have the same problem as you described. Edit: I found the answer, and it wasn't in fixing the 3DConnexion driver as I supposed it was. The solution is in FreeCAD itself. Go to Tools>Customize> Spaceball motion or buttons. I now ha...
