Boundary for wave equation

Please login with a confirmed email address before reporting spam

Hello everybody,

Do you have an idea about how can i define a "wall boundary" in pde solving module of comsol ? I'm doing acoustic without the acoustic module to better understand what's going on (i'm a student) and i need reflection boundary, but i don't know what to choose among the lot of choice. Wall boundary are part of neumann condition with a zero normal speed on the boundary, do i have to implement it somewhere ?

regards,
irene
