I have attached the screenshot of a pressure graph.please let me know what the x,y and z axis represents.

x,y and z are the spatial coordinates of the model, what else? The picture obviously shows pressure on a 2D slice of the 3D model.

Thanks Edgar

one more thing..I would like to ask is that why do pressure values are coming negative in the vertical bar on the right side.

Hi

on your fist graph it looks like you have a rather coarse mesh, perhaps too coarse, on the second I suppose that the sign comes from the surface definition, pressure is defined to the external surface normal. Could that be involved ?

Good luck
