Solver Settings for time-dependent analysis using a viscoelastic material

Please login with a confirmed email address before reporting spam

Hi everyone,

I am trying to solve a Fluid-Structure Interaction problem where the solid is a viscoelastic material. I am using the material model included in COMSOL v3.5, so I just specify the bulk modulus, shear modulus, and prony series for three dasphot-spring sets (Generalized Maxwell Model).
I want to do my analysis time-dependent, and there is where I get very confused.
Does anyone of you know how to set up the solver settings for this?
In the documentation is written that we must "initialize" the problem first, so I understand that we should use the analysis type "viscoelastic initialization". But, does that mean that I should run the model stationary first, then store the solution, and then change everything to transient? Or should I keep the viscoelastic initialization analysis type, but then change manually the solver to time-dependent?

Thanks for any help I can get!
Bernardita
