Hello, for several days I started using the Ansys Polyflow program. I set Geometry, Mesh, Setup and when I want update solution I have a problem. I am sending the description below.

"At least one bad element has been detected in the mesh.
******* The worst has the following feature (s)
******* Negative Jacobian in element 45, (x, y, z) = (0.007445, 0.03399,
********* 0.005009).
******* Too small angle in element 45, (x, y, z) = (0.008113, 0.03491,
********* 0.005691).
******* Too big angle in element 108, (x, y, z) = (0.00317, 0.021182,
********* -0.0013973).
******* Non-convex element 54, (x, y, z) = (0.005922, 0.031249, 0.003263).
***** This can lead to local inaccuracies and possibly convergence
***** difficulties. It is strongly recommended to fix the mesh. "

Can anyone help me? What can I do to get rid of the error.

Greetings,
Adrian
