hi,
i have designed a pressure sensor... i am getting different displacement values as output but deformation for all applied pressure is same....why is it so??? wat should i do to get the deformation corresponding to applied pressure

Hi
what do you mean by deformations are the same ? is it on the 2D or 3D graphics with deformation sub node ?
If so it's probably the automatic scaling between the different pressure values, the displacement appears the same, but the units of the scale changes each time => set the rescaling factor to a constant value
Another way to check is to cut your membrane by a Data Set cut line (or by having the geometry split in the middle of the membrane), and you do a 1D displacement ) or better (u,v,w) line plot across your membrane, for all parametric pressure values, then you have everything on the same scale

Good luck
