Elmer Discussion Forum

Hi Mika, thanks for your answer. Two questions: 1. Constraints are only needed for PBC, correct? CBC should work by replacing indices if I am not mistaken, so the requirement of conformity will always be fulfilled. 2. Do you know whether this change in the routines will happen soon? Thanks and regar...

Hi everyone, I am no sure whether I have spotted a mistake within the TimoshenkoBeam solver (unlikely) or whether I do not understand the conforming BC (CBC) correctly by reading the Elmer documentation (likely). In my current project we need to create a number of pure beam networks with periodic bo...

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

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 assum...

Hi everyone, first of all thank you for the nice package that you provide. Second: I want to use elmer for topology optimization and as a test case want to implement the standard problem of maximizing the stiffness for a cantilever beam as described here https://www.mdpi.com/2073-8994/13/4/712 or in...
