Re: Different results in coupled eigen-helmholtz analysis

I believe symmetry models can only calculate symmetric modes .

Re: how to add impulses in Elmer

You can use MATC to input as a function of time or use tables, see the MATC manual

Velocity = Variable Time
Real MATC "if (tx <= .01) (tx/.01)*200.E6; if (tx > .01) 0.0"

Re: fsi about artery

The sif and mesh files help others figure out what the problems to be solved are.

Re: Scalar field inconsistency at geometry face border?

Perhaps the mesh does not share nodes at 1. Did you check for coincident nodes in Salome?

Re: Application to complex mechanical assembly

If you require contact surfaces between the parts in the assembly then I would suggest CalculiX, it is also open source, Calculix is much more focused on solid mechanics. Elmer is very good at fluid, heat, and multi-physics. I think you should take the time to learn Elmer, not for this problem, and ...

Re: Result becames strange in an edited model

The target bodies and target boundaries changed numbers, was that intentional? Difficult to review without mesh files.
