I ran a test on the B3 saturation benchmark. The two-fold DOF reduction from 45803 (Q2P1) to 19803 (Q1P1) yielded a reduction in simulation time by about a factor of 4. In addition to the DOF reduction I reduced IP number from 4x4 to 2x2. Results show only a slight shift, simulation is stable against pressure oscillations (storage and drainage sufficient). This can be a feature in HM, THM, etc. also! |
The constexpr value allows some decisions to be made at compile time.
The reference files are converted from the second order mesh results with the 'convertToLinearMesh' utility. Note, the sigma, and the NodalForces fields do not compare well to the higher order results, but other variables do very well. sigma, probably due to extrapolation; NodalForces because of the missing middle nodes which would take some of the load.

FYI; Compilation time roughly doubles, so does the memory usage. |

ORDERto shape functions.Allows linear-linear shape functions in the RichardsMechanics process. So far only quadratic-linear combinations were possible.
Compilation times (for the RM process) are skyrocketing, as well as memory usage while compilation.
