Hello everyone,

thanks for reading!

In my Model study.1

I'm using boundary loads to deform the material below(Fig.1),

then I want to keep this deformation fixed and add viscoelastic model to analyze this material's stress relaxation,

Is there any way I can achieve the above operation ?

( I have tried using Study.2 to inherit the results of Study.1

But I just can't find the way to fixed the deformation....
