I am conducting a study using the stress analysis features in creo simulate but I can't explain the steps the process is taking. I am using the multi-pass adaptive convergence method using maximum von mises stress as my measurement with a targeted convergence of 1%. I set the minimum P-order to 1 and the maximum P-order to 9.
What I can not explain is why this method is using only 7 passes to calculate a solution. The solution is not converging until the 9th order bias functions so it is not stopping because it has converged.
I would expect the method to run a pass for each polynomial order and increase those elements that have not yet converged until the maximum p-order is reached or all elements have converged. The method appears to be skipping a couple of these passes for the 3rd and 5th polynomial order.
I have attached the run status summary file from my analysis. It can be seen that the second pass uses 2nd order functions and the third pass jumps to 4th order functions. the same jump can be seen between the fourth and fifth passes.
I tried setting the maximum p-order to 3 and the results returned a maximum p-order of 2. If I set the maximum p-order to 4 and the results returned a maximum p-order of 4 and included elements with a p-order of 3.
Can anyone can shed some light on why the multi-pass adaptive method is not running a pass for each p-order or why the solution returned (which had not converged) when I set the maximum p-order to 3 did not include 3rd order elements.
Thank you,
