How to simulate torsion of cylinder in ANSYS?
Wed, 2010-12-15 05:53 - sspadhee
I want to model torsion of a homogeneous hollow cylinder in ANSYS. I changed to cylindric coordinate system also. But each time I run the program the result is that of bending. I have attached the mac file and output file for reference. Please advise.

There are many
There are many approaches to simulating the torsion of a model in ANSYS.
Please see the code below (MPC method)
