Quick question: Dynamic viscosity

I understand that a solid should have "zero" viscosity, meaning it doesn't flow. Which in turn means that the viscosity is infinite. So many of my materials need me to input a dynamic viscosity value, but how do I indicate to comsol it is infinite? Is there a specific designation? Do I just use an extremely large number?

A quick google search didn't turn up much.

Thank you

If you define the fluid and solid domains correctly in the physics you are using, Comsol doesn't ask you to enter the viscosity for solids.

Yes, it sounds like the same mistake and solution as in this recent thread:
