Re: cartesianMesh - regex won't work in custom meshDict

Hi all, I am delving a little deeper in customizing my meshes generated by (the excellent!) cfdof wb, and am noticing that regex's won't work as expected. i.e. this: localRefinement { wingtop { cellSize 0.005; // [m] refinementThickness 0.03; } } will happily work but this: localRefinement { wing* ...

Re: Strange cfmesh behaviour...

Hi all, just doing some simple exercises, and not getting any satisfactory results. I'm trying to do a very simple cylinder-in-flow benchmark; 500mmx400mmx10mm volume with a 10mm radius cylinder: cad.png meshing 2d cfmesh, base element size 10mm, with a mesh refinement of 0.1 relative on the cylind...

Perfect - thank you very much!

I must say, as a long Alias/Catia user but only recent Freecad user, I'm very very impressed with it and it's extensibilty, especially cfdof. Never expected it to be so good, and that coupled with such a great community. Excellent!


Kai.
Thank you!

Re: Showing the Courant number / delta t in residual plot

Hi all, I was wondering if it's possible to show Courant Max/Mean and timestep in the residuals plot, while the solution is running it's possible to keep a closer eye on it. In report view they just wizz past too fast... This would be quite interesting in tuning the simulation. Many thanks for any ...

It may be that openfo...
