Information about p-elements in Creo Simulate

[ME_9860339]

Hello community,

in the context of my master thesis, I want to consider the possibilities of Creo Simulate.

I know that Creo Simulate uses p-elements, whereas e.g. Abaqus uses h-elements.

I also know the general principles behind the two methods, but I could not find any detailed explanation of the element formulation in Creo Simulate.

So e.g.:

- are p-elements basically h-elements, but only with higher polynomial order? Or is there a basic difference in the formulation of p-elements?

- do the p-elements in Creo Simulate also have midside nodes?

- are the elements in Creo Simulate isoparametric?

- does Creo Simulate use numerical integration, calculate stresses at integration points and extrapolate them to the intersections of the plotting grid?

If you have any explanation or know a good literature, I would be thankful for your answers.

Many thanks in advance.

The product was formerly named Pro/Mechanica. If you search for information using this name then you may find more information. If you can find old Pro/Mechanica documentation that will probably be your best starting point. PTC used to ship voluminous sets of books with the software that was much more complete than the on line help they currently use.

Many thanks for your reply.

Here is a comparison of H/P elements (in Pro/MECHANICA and ANSYS):

Thank you very much for the shared information.

I think that this will help me a lot and be a good starting point!

You're welcome.
