rheoFoam solver

[sunil-27]

While running basic case channel flow, using the RheoFoam, I'm facing the following issue
rheoFoam: error while loading shared libraries: libHYPRE-2.18.2.so: cannot open shared object file: No such file or directory.
Can you please help me out with this?

The error tells you that libHYPRE-2.18.2.so is not in your LD_LIBRARY_PATH (the .so either doesn't exist at all or it could just not be found). Several reasons could be behind, e.g. a bad installation or an incorrect definition of LD_LIBRARY_PATH in your .bashrc.

Thanks, it's working by appending source with lib path.

I'm trying to simulate fluid flow in idealized stenosis axisymmetric geometry, I have considered sPTT constitutive equation to model fluid and pulsatile inlet condition with time period T using rheoFoam solver. At the time step (T/4) vortices formation occurs at the post stenosis region, with an immediate effect there is a surge in courant no. I have done multiple trials to get rid of the rapid rise but nothing had worked in lowering them. Could you please help me in this regard?
