cosmosexpress stress analysis software for accuracy
(OP)
Hello,
Does anyone have any problems with cosmosexpress
stress analysis software for accuracy.?
I ran a test simple stress analysis on a round solid
rod with applied pressure at 5000 psi on one end and
fully supported at the other end. So the maximum
stress should be the same as applied pressure but the max. stress according to
cosmosexpress was 6800 psi.
So something is not right, I may be missing some setting I don't know about or
the software??
If anyone know the answer to this or a way to tweak it to have accurate result as temp. fix, please let me know

The Max. stress showed around the OD of the part.
I'm just wondering how reliable is this software.
It may have limited restraint feature. If you have cosmoexpress, please try this simple problem on yours see if you get the same results.

CosmosExpress is very limited in the type of problems it can analyze accurately. It does not have the Restraint options that are required to analyse practical problems as you cannot fix each direction independently.
I recommend using an FEA software that supports restraints that can control specific directions. CosmosWorks linear static capability is a good starting point.
Of course, any software is dangerous if not used properly.
