My results are changing with change in the density of mesh in the non linear analysis. There is no option of P and H controls in the non linear analysis. What can I do to get stable results.
The model is a large sheet of 2012 mm length x 992 mm width x 5.8 mm thickness. the sheet is fixed at four supports and have a pressure of 2400Pa acting on the top surface in the downward direction.
I will appreciate any comments/suggestions or tips.
Thanks in advance.
