Hi,

I am trying to solve fluid flow problem in a periodic tube by the solver simpleFoam. The fluid is incompressible and flow is laminar. I have imposed the noSlip condition on the tube wall and applied wedge condition as an axisymmetric condition. Also, I have imposed cyclicAMI condition as a periodic condition at the inlet and outlet. When I run the solver simpleFoam in the terminal, I find the error message as in the attachment.

According to the instruction in the message, I have changed the matchtolerance. But still get the same error.


It is mentioned that I have constructed the tube geometry in GMSH and produced the unstructured mesh in GMSH.


Any suggestion will be very helpful for me.
