Any help?

Hello guys: I am a newbie to Elmer and I am trying to model an aircraft wing using the linear plate solver. The wing (a cantilever beam) is orthotropic and has E_1, E_2, G, mu parameters given for it. However, I am unable to assign those values as the plate solver allows for to assign only E_1 and m...

Hi Peter, I am indeed using this functionality to couple a Emer CSD code with a CFD solver, where I obtain the nodal forces for structural boundary nodes from the CFD solver. I use the following boundary condition in Elmer sif file to impose the nodal loads obtained from CFD solver: Boundary Conditi...

Thanks peter. It works now. I just want to know what was changed in the source code. Is it that you now save displacements from several of previous iterations, or you use different time-descritization strategy for 2nd order PDEs. Also, with this implementation, I don't think we need to use 'Calculat...

Any luck? I am facing the same issue. I think we need a way to communicate the acceleration info from previous time-step to resolve the issue?

Stan, were u able get hold of the issue?

I am facing the same issue. I am getting numerical damping and bias in frequency when restarting the transient simulation at each time step, when compared to the response obtained without stopping. Did some one found the solution to this issue?
