Elmer Discussion Forum

Hi everyone,

I need to export the global stiffness matrix without boundary conditions for beam networks for some research project, but I am not interested in the actual simulation.
1. I can already export what I desire (see attached), but how can I stop Elmer from starting the simulation?
2. I assume the global stiffness matrix is given in the global coordinate system and since I export it for beams the degrees of freedom are ordered for each node like this: displacement in x,y,z, moments due to torsion/bending around x,y,z. Correct?

Thanks and regards
Stefan

You could just kill the process after it starts or try to use the solver control

Execute Solver = Never

there are lots of option such as always, after simulation, before simulation, never, ...

Hi,

If the solver is never executed there will unfortunately be no stiffness matrix. You could however, try this keyword in Solver section: There might be other ways, like setting linear system iterations to zero etc. but this one should be clean. Codewise it is DefUtils.F90 line ~3519. Had to check it up since this is rarely used.

@Peter Thanks. That's what I was looking for.
