gudiya New Member sreya Join Date: Jun 2009 Posts: 3 Rep Power: 16	hi all, i am trying to do a dynamic meshing using DEFINE_GRID_MOTION where i am shrinking an object in the x axis, keeping the volume constant, i.e it bulges out in the y axis. it is a 2d problem. i have given a WALL boundary condition to the inlet, and all i want is to shift this boundary condition along the x axis as the geometry shrinks along the x axis. can you suggest me a way to do that? it will be of much help thanx
