Thanks, W. for confirming that! I reinstalled deal.II after installing Trillinos. Step 31 runs well.   From: Wolfgang BangerthSent: Wednesday, June 16, 2021 4:10 PMTo: dealii@googlegroups.comSubject: Re: [deal.II] Re: Integrated material and spatial traction forces on boundary not equal On 6/16/21

Hi Wolfgang, I tried a quadratic element, and was able to reduce the number of degrees of freedom for the same level of convergence by another order of magnitude. Thanks! Best, Alex On Friday, June 11, 2021 at 3:34:08 p.m. UTC+2 Wolfgang Bangerth wrote: > On 6/11/21 4:04 AM, Alex Cumberworth

Hi Alex, I'm learning deal.ii and trying do the similar verification. If it is possible for you to share the code with me? Thank you! Michael On Tuesday, May 11, 2021 at 4:46:55 AM UTC-6 alexanderc...@gmail.com wrote: > Hello, > > As a test to validate my code, I am solving the equations for >
