hello,

I am shooting a pulsating flow of water into a straight tube. I would like the tube to deform from the pulsating pressure. Can this be done by just using the deforming mesh options without using a udf file? thanks.

I already tried it, but don't remember anymore since we switched to OpenFOAM.
But I believe it is: DEFINE_GRID_MOTION
