Hi Peter, yes you are righ, I was just trying to understand your question and it didn't work :) what do you mean by special BC? the interface between pressure and frame surface speed/displacement? About the displacementent field, I have done some further investigations. I have taken the mesh points ...

Sorry, I'm not sure I understood your question. I have checked the displacement excluding force BC and leaving only displacement BCs; the displacement field and the pressure field were all zero. Is this what you were interested in?

Hi Peter, in theory it should, I have drawn the steel frame to be simmetric. I have checked the position of all the points in gmsh and they all coincide, steel characteristics are homogeneous (taken from the library), and indeed the deformed size and length coincides. If there is any other reason th...

Hi Peter, I apologise for the huge delay in the replay, I had to leave the project until a couple of days ago. I hope that the topic is still considered open :) After some thoughts and considering the complexity that was starting to come out ferociously I had a closer view to my problem (and elmer m...

Hi Peter, thanks for the input, I have the model working :). Just a quick doublecheck to be sure that I'm doing everything ok, I have to apply the MeshUpdate solver only to the structure domain and than propagate its mesh speed to the fluid domain through interface boundaries. No problems with incom...

Hi all, this is my first message in this forum so first of all let me thank all the people involved in the Elmer project for giving us this very nice tool. It gives anyone the opportunity to visualise things that you could only imagine of before!! :D But going now to my problem, looking at elmer man...
