Adaptive periodical representative volume element for simulating periodical postbuckling behavior

Finite element method (FEM) with fixed representative volume element (RVE) encounters some difficulties in simulating the periodical postbuckling behaviors of infinite long beam or infinite large film on soft substrate under compression, because the wavelength and pattern of buckling are not known before simulation and will change with the increase of compression strain.

Post Buckling Analysis using Nastran Sol 106

Can anyone help me out to resolve DMAP Fatal Message 9061(IFPL) - the version requested on the restart FMS statement is not valid for restart purposes. subsequent restarts should reference a prior valid version.

What this error and why it is happening?

Thanks in Advance
