Ejection step in injection molding

I am trying to simulating the ejection step of injection molding process using Comsol.
After filling plastic into mold cavity, and packing stage, the solidified plastic part is ejected out of mold.
Before the plastic part is ejected out of mold, the plastic part is constrained in the mold. The residual stress accumulated during the filling and packing stage(solidification) will be released when the part is ejected out of mold.
Can anybody give me suggestions about how to model the ejection of plastic? I know the boundary conditions should be set to ambient conditions,i.e. the fixed constraints is removed and set to 0. But It doesn't work in comsol.
Thanks.
Eric
