Hi,
I am trying to setup a simple fluid simulation.
I create cylinder which will be the tube and a torus which fluid will flow around.
I combine them by using boolean cut (I think I suppose to do it this way?).
Then in CfdOF workbench, I add the boundary condition and them meshing it with gmsh.
But I got this error below.
Thank you in advance for help.
I install FreeCAD, openFOAM, and gmsh from openSUSE Tumbleweed.
