How to build the axisymmetric model in Abaqus CFD ?
(OP)
Need help to build the CFD model of the ball valve in Abaqus 6.11-3 (see picture).

The problem is that calculation 3D model takes a long time.
I tried to build 2D-planar model (see right picture) where:
1 - wall, 2 - inlet velocity, 3 - outlet pressure, 4 - symmetry BC (normal velocity = 0)
But such simplification is not correct because in that case we got the cylinder but not the ball.
Is it possible to build the axisymmetric model in Abaqus CFD ? How to set the axisymmetric Boundary Conditions ? I attached the model file.

IF, on the other hand, you are trying to model something like a ball check valve, then pick the pipe axis as the symmetric axis.

For example this simplification of the model is correct?
where 1 - faces with symmetry Boundary Conditions (normal velocity = 0)
These symmetry Boundary Conditions are correct?
