Suggestions for a 2D Oldroyd-B channel flow software
Hello guys. I simulated a simple planar channel flow with an Oldroyd-B viscoelastic fluid model using OpenFoam 9 with RheoTool.
The idea is simple, I need a channel length of 10 m and a channel height of 1 m (again, the simulation is 2D). The boundary conditions at the inlet are u = 1 m/s pointing in the streamwise direction, null polymeric stress and null gradients of pressure. At the outlet, null gradients of velocity and stress and null pressure. At the walls, null velocity, and linear extrapolations of pressure and polymeric stress.
Thus, nothing really complicated and it worked well in this software. However, my advisor asked me to try other FREE software/code to simulate to see if we get the same results.
I tried Basilisk but apparently it does not likes non-squared geometries. Any suggestion of FREE softwares/codes?
