Dear All, I am trying to solve an elasticity problem and am dealing with p-refinement. With global refinement, my solution is as expected (correct). I am using an initial mesh of 4X2 elements. If I keep p=1 for all the elements, and make p = 2 for the 7th element, the solution is still correct. However, if I use p=2 for all the elements and make p=3 for the 7th element, the solution suddenly becomes completely wrong. Choosing the 7th element is just arbitrary, other choices also show the same problem.
Since it works for the combination of p=1 and 2, I do not think hanging nodes are a problem. I looked at the hp-paper as well and do not see something that might be going wrong related to the hanging nodes. I am still trying to narrow down the problem and come up with a simplified example, however, I still thought of raising this question. Based on the above scenario, can someone figure out what might be going wrong?
