[ANSYS Meshing] Meshing a Simple Pipe With Different Diameters

Adnann · May 9, 2016, 05:14

Hello folks

.

Currently I want to simulate a Fluid-Structure Interaction (FSI) analysis. I want to simulate a flow that goes through an orifice, and how it affects the pipe and Flow-Induced Vibration of the pipe.

However, I'm having trouble meshing the pipe and orifice. I used the default meshing, but the results look very terrible, with very high Skewness. I understand that this is a case of pipe with different diameters. Can anyone help me? Attached is the design of my geometry

use help section in Ansys to understand how meshing is done.

Ah thank you for the help

In any case I have just finished one System Coupling analysis. However, after 100 coupling steps, the solid part of the analysis is converged but not the fluid.

How do I increase the number of coupling steps? I could not seem to find it
