Dear all,

I am trying to run a dynamic mesh motion simulation (foam-extend-3.2) with a floatingBodyMesh.

During the run I am trying to write the patch of the barge at regular intervals using swak4foam

planesAndContours
{
type surfaces;
outputControl outputTime;
fields ();
surfaceFormat vtk;
barge_wall {
type patch;
patchName barge;
}
);
interpolationScheme cellPoint;
}

Here is the problem: the barge points are not updated! So it keeps writing the barge at position time=0, whereas the full data field write the changing mesh points

I found in one of the swak4foam presentations that dynamic mesh handling is not by swak4foam, so I am looking for an alternative way to do write my barge patch

Does anybody has experience with writing patch during dynamic mesh motion runs?

Any hints appreciated!

Regards
Eelco

I know that sample can dump a patch as a VTK, you might be able to fold part of the code into your solver and have it write the patches out on the fly as well.
