structural analysis Post processing results
 

I recently started using the Ansys workbench for my thesis project, and I would like to ask what is the best approach to show the post-processing results?

For example, I had run a transient structural analysis simulation, and I got a result, i.e., deformed body,

how will we compare the deformed body to the original geometry to find changes in volume or diameter, etc.?

or is there any better way to show my results for people to understand in an easier way like to show in my thesis report

I saw some approaches like using probes, but I am searching for a new and better way to show my results as a body got deformed, and this is the diameter change or volume change.

This sounds like you are doing an FEA simulation, that is stress/strain. This is the CFX forum, it is not an FEA software. Try a forum about ANSYS Mechanical.

post processing results
 

First, i did cfx and got heat transfer coeff for that continuation transient thermal to calculate the cooling time of a body and then finally transient structural analysis to find how deformations were

do you know anything to help?

The deformations are a FEA thing. Use the ANSYS Mechanical results objects to analyse these. For comments on how to do this try the Mechanical tutorials and forums. This forum is for CFX, so that covers the heat transfer side of things.

U can see deformed on two ways
U can turn on undeformed wireframe
Second U can define deformation factor to plot overscaled deformarion

Hopefully you did the HTC correctly? What did you use for your bulk or "ambient" temperature in FEA?
By default, CFX uses the node adjacent to the wall to calculate HTC, which is mesh dependent and not the same as normal bulk temperatures. See the FAQs for more info on HTC.
