Hyperelastic anisotropic material modeling problem

I have a hyperelastic anisotropic modeling problem. There is a swelling for the the body. That is to say, the determinant of the deformation gradient equals a fixed constant other than 1. Does anyone knows how to impose such constraint in Comsol? Thanks for your answers.

You can simulate the effect of swelling by adding thermal expansion to the hyperelastic material
