Re: Write Mesh times out only with refinement mesh

I am having no luck. I have changed the order of operations, the size of the mesh, and the only thing that works with this model is if I only run the initial mesh. Mesh refinement goes on forever, or several hours before I kill it. I have not tried putting the armillary in the middle of the cube in...

Re: Simulation exited with error

Hi all, I try to run the basic CFD tutorial 1 I found there http://www.opensim.co.za/training.html... All well done following the tutorial... But after solver starts, nothing happens (no convergence curves) untill this error message : "Simulation exited with error", few seconds later. Pleeaase help...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

But does thie suggest that I can't repeat all the historic static pressure inputs that I successfully condicted with FC 0.17 and the old CfdOF? I'm trying to CFD existing physical testing that I conducted many years ago. Ah. I didn't realise that this setup was working previously. If you still have...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Okay Oliver, let me take you through it as I run the existing case after a reboot of my notebook. 1) - Took a look at my temp folder and meshCase was there 2) - Opened the model case 3) - Ran the model and wrote the case 4) - Ran Solver and immediate simulation exited with error 5) - Additional fil...

Re: CFD tutorials from opensim - UAV - 03 macro

First, thanks to all who have brought this to FreeCAD; I am learning so much. I have worked through the opensim tutorials, however, I have a few questions about some of the details. The CFD - UAV tutorial runs OK, but has some differneces from the documentation included. In macro 03-refineMesh.FCMa...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Hi Oliver, Still exploiring. Remeshed again (cfmesh) with a larger mesh size after a reboot so empty temp folder. Same error with no files in temp folder again. 12in VSA Diffuser Only - Rev P1 cfmesh Mesh.PNG12in_VXA_Diffuser_Only _Rev P1.FCStd Michael Could you confirm that when you create the mes...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Thanks Oliver. First of all, this is a question I was intending to raise. Are you suggesting that I dont have to use the temp Default output directory and I can make one for each case to ensure that it is not lost? Yes. You can click on the CfdAnalysis object and set the Output Path on the Properti...
