Error importing Abaqus mesh
Hi everybody! I have a mesh created with ICEM CFD that I would like to import in Elmer. There are several export format such as: GEOMETRY -> IGES, DDN, Parasolid, Rhino, STL MESH -> Abaqus, Ansys AutoDyn, Exodus, Ideas, LS-Dyne, Nastran, Patran, Radioss, FE Modeler, STL, Spectral elements I tried An...

Re: Pressure waves FSI - [Cochlear simulations]
Hello Peter, thanks for your response. I approximate cochlea with two channels separated by an elastic membrane. In this case typical dimensions for the cochlea are: * height of a cross section ~ 2 mm * width of the oscillating membrane ~ 0.3 mm * thick of the oscillating membrane ~ 60 micro While e...

Pressure waves FSI - [Cochlear simulations]
Hello everybody, I have an initial model of the cochlea where the membrane is deformed by a flux between two surfaces: http://youtu.be/yJjY9HBJGTU However, in real anatomy, the cochlea is a closed partition where there is no flux across boundaries. The boundaries are elastic and a pressure wave is w...

Re: Flow and deformation in an elastic tube
Thanks Peter! I'm really getting caught up in using Elmer
I'll do some more investigations...

Re: Flow and deformation in an elastic tube
Thanks Peter! I tried and indeed it worked beautifully. I post the complete solution in case someone else is looking for it. I also used: * non-linear iteration 1 and relaxation factor 0.5 * gradP discretization I made a short animation in which pressure is the background color, wall displacement is...

Flow and deformation in an elastic tube
Dear all, I was trying to repeat the FSI validation experiment [1] in which an elastic tube is deformed by a passing flow. I tried to build up the solution using both the tutorial on fluid-solid interaction and the suggestions to Emilie's post (http://www.elmerfem.org/forum/viewtopic.php?f=3&t=3...

Re: Elmer in cochlear simulation
Hello Peter, Thanks for your response: I'm really flattered that you had the time to write such a detailed and long answer! I wasn't aware of all these subtleties between Elmer and OpenFOAM. I found especially interesting when you explained the importance of modelling within a single software to obt...

Elmer in cochlear simulation
Hello everybody! I would like to use Elmer to model the response of the human cochlea to a sound. I would like to ask: * Which are the advantages/pitfall of using FEM against finite volume approach (openFoam) to model FSI? Are they equivalent? * I was thinking to modify tutorial 8 (Interaction betwe...
