Using Helmholtz equation

Please login with a confirmed email address before reporting spam

Hello, I am trying to simualte non local damage in hyper elatsic material, For this I am using Helmhotz equation , The source term is elatsic energy (Neo Hookean) which is defined in comsol itself. For using this energy as a source can i directly use one which is there, If yes, how? or should i define its expression in variable and then use that ?

You can use the built-in variable for the strain energy density, but you must use the full scope, like 'solid.Ws'.
