pimpleDyMFoam dynamicMesh nonuniform ramped displacement
Hi,
I'm a new registered member of this forum but I used this forum a lot in the past years to solve my problems. So thanks to you all for this great community.
Unfortunally I have a question which I havent found here.
I'm working with pimpleDyMFoam for a FSI with Calculix. For the transmitting of the nodal displacements from the structural solver I'm using the BC "fixedValue".
Code:
/*--------------------------------*- C++ -*----------------------------------*\

object pointDisplacement;
}

.....
Each new timestep then has the proper internalField from the solution before. However the fixedValue gives a shock to the system at the beginning of each FSI Timestep, which crashes my simulation after a while.
I searched a lot for a ramped version of a nodal displacement BC. However all ramped BC's are uniform. So therefore, only the whole patch is deformed and I can not give a point wise definition.
--> Do you know a BC which can handle nonuniform ramped pointwise displacement for the dynamic mesh?
Thanks a lot in advance.
