Recompute Preconditioner

Post by Franz Pichler » 08 Nov 2016, 21:02

Hello Dear Elmer Team,

i just wanted to try out the

Linear System Precondition Recompute =Integer 20

feature of elmer.

I have a solver with 2 dofs and a linear constraint matrix.

Somehow the keyword causes no reaction at all.
What i figured out myself, is that the solver%matrix%iluvalues are never associated before or after the call to defaultsolve.

i use bicgstabl and an ilu2 preconditioner.

Are there any keywords that enforce saving the iluvalues or did i miss something else??

best regards
