[GeomechanicsApplication] Geo/linear elastic strategy #12479

Open aronnoordam opened 1 week ago

aronnoordam commented 1 week ago

added another strategy and builder and solver meant for linear elastic problems.

Mostly, this strategy exploits the fact that the internal forces dont have to be recalculated every iteration.

stiffness matrix is constant
damping matrix is constant
mass matrix is constant
rhs, only condition contributions are updated
the linear system is pre factorized in the first iteration/ time-step

Only external forces are updated
