Dear Friends,

I'm using *SURFACE BEHAVIOUR option with PRESSURE-OVERCLOSUR E=EXPONENTIAL for my door analysis.

I have used c0=.01 and P0=1 in 1st case

and c0=0.01 and P0=100 in 2nd case

and getting different displacement value at the loading nodes.

So anyone tell me the significance of both the runs and which result i assume to be close to the real.

And if i have removes the PRESSURE-OVERCLOSUR E relationship then my run terminates with the error of convergence problem.

Plz help me out.
