Dear all,

I meshed one-third swirl chamber and tried to calculate a water pressure drop through the tangential holes using interFoam.

As results,

1. The velocity vectors are seemed to meet a wall near the cyclicAMI boundary condition
=> I'd like to know if there is any fault in setting the boundary condition

2. The calculation blew up after few iteration.
=> I'd like to know why I get the floating point in this case. Is this a mesh quality problem?! (In this case I didn't apply the viscous layer)

The test case with salome py code is attaced.

Thank you for your help in advance

As a consequence, there was no issue for this set.
There maybe some trivial mistakes during meshing with salome.
But with the lower version of OpenFOAM it could spit some err message for the cyclicAMI BC.
