Hi Saurabh,

Thanks for the inputs. Meanwhile I was trying to solve it by changing various analysis settings.

Originally, I did this as a two step analysis, in the first step the initial displacement was given and in thze second step the diaplacement was deactivated. When I did the analysis first, I had turned on the ‘Auto time stepping’ and ‘Large deflection’ ON for the second step. But when I turned both of them off I got a much better result (given below). I was curious about what do these two settings do to the problem that the result varies drastically??
