CFX-Structural thermal stress analysis

Ravikiran · February 22, 2010, 00:33

Hi,

I am working on a fluid-solid thermal stress analysis project. And a newbie to ansys.

Brief: A big cylinder ( 20 m length and .5 m dia ) with around 900 inlets and 2 outlets. Supersaturated Steam of diff temps and mass flow rates enter through various inlets and mixes in the stomach of cylinder, comes out through 2 outlets.

Aim is to get a thermal stress distribution in the sold material.

I have used ICEM CFD to mesh and obtained temperature distribution using Ansys CFX for both the solid and fluid domains.

Now i have to export this temperatures to ansys structural and apply as loads.

Some one please guide me how to go about from here i.e, instructions on export, import,etc..

If there are any specific tutorial for this, tell me where can i find them.

Thank you very much in advance.

Ravi kiran.

So you need to export the 3D temperature filed from CFD-Post and apply as a body load in ANSYS. This is a beta feature in version 12. For what I recall, there a few things that can trip you up when doing this, so it would be best to get advice from ANSYS support.
