Reaction forces #140

Open srosenbu opened 1 year ago

srosenbu commented 1 year ago

I am not exactly sure what happens in the calculation of the reaction forces, but the current approach seems to be unnecessarily complex.

https://github.com/BAMresearch/FenicsXConcrete/blob/304d2b91affeb2c7691b1a21082ac319bd399c16/src/fenicsxconcrete/sensor_definition/reaction_force_sensor.py#L78

Imo, it should be enough to sum up the nodal forces. This can be done on residual.vector.array directly

not sure if the residual vector actually contains the constrained dofs?
