Expanding to 2D wave #3

Hi and thank you for your contribution!

I'm trying to expand the 1D wave equation example to 2D with slightly different conditions as follows:

f(x,5,t)=f(0,y,t)=f(5,y,t)=f(x,0,t)=0, where all the boundries are absorbing (zero) a source function f(0.5,2.5,t)= 2 * sin (2 pi t) and an initial condition f(x,y,0) = 0

I'm not sure if such a time-dependent source term is possible to implement. This is my attempt, but the results are not really good.

Please assist me with this implementation, as I would love to include the results in my research.

Our implementation is not based on DeepXDE. Please contact the DeepXDE developers to seek assistance with your case.
