You did not mention the type of surface, but in real life an extruded polymer
is under stress and you must restrain the ends. As in real life a heated
uncrosslinked polymer will shrink. The system probably behaved appropriately

Dear GMX users,
I study the interaction between polymer and surface interactions. Polymer
parameters were prepared by cgenff, and the parameters of the surface were
solved by INTERFACEFF. I performed short simulations, however, the system
was shrunk. I used the standard mdp file of charmm-gui memb
