Hi everyone!
i'm at the very first steps with comsol.
i'm building a model that simulates the tumor growth. the equations that describe the growth are initially defined in a spherical small domain (the tumor), then i have a bigger domain that contains the small one. Since i'm studying the tumor growth obviously the tumor domain is not fixed but it changes its shape and size along the time. i used the level set function to track the tumor domain interface along the time but i don't know how to write in comsol the free boundary conditions for the tumor equations. Using the classical option: "boundary conditions" i can only specify the initial tumor boundary while i have to define the boundary conditions on the moving interface. How can i do that?
All suggestions gratefully received.
