Information about p-elements in Creo Simulate

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.
