Modifying the Const. equations

Hi

I am new to COMSOL 4.2a and wondering if i could modify the constitutive equations of the material model ( e.g. the equation for the visco-elastic stress computation).

i want to add a bulk stress computation with bulk modulus K and add to the existing shear stress term.

is there a way to do that in COMSOL 4.2a ( would you tell me how to do such modifications)?


appreciating your suggestions

-Tesfaye

Hi

try s a search on the Forum, and check the COMSOL conf papers on the web, you can adapt most parameters equations in COMSOL, all depends exactly what you are trying to do

Good luck
