abbreviations for physical parameters

Dear all;

I am learning comsol for specific models and found a potential of comsol for the models.

But, I am not sure how to input diverse physical parameters such as strain rate in the equation. For example, I want to implement my own rheology in the dynamic viscosity.

dynamic viscosity = constant1 * strain_rate^2 + constant2 -> Just like this.

In the manual, I found some abbreviations for physical parameters such as strain rate. But, can I see a list showing all the abbreviations for physical parameters used in the comsol? T = temperature, P = pressure, g_const =gravity so on. I want to see the list including all the parameters.

Please let me know the list if exists.

Thanks.
