Higher order elements

[Hermes Sampedro]

Dear all, 

I would like to ask how to handle higher-order elements. I would need to use 4th order. Looking at the first tutorials, I found that using FE_Q, it is possible to use only 1st and 2nd order.

Thank you

[Wells, David]

Hi Hermes,

We typically use lower-order elements in the tutorials, but FE_Q supports arbitrarily high degrees - for example, step-48 uses degree 4 elements, and the hp tutorial programs will use up to degree 7 or 8. We don't have plots for these shape functions but they are implemented.

Best,

David Wells
