Hi,
I have tried to simulate propagnation with two line source. For doing that I have initialized to "1" some positions as a vector, located at the first line of the source mask and the rest initialized to "0".
That doesn't work unfortunately.
But, it work with just one position initialized to "1", as a ponctual source.
This link helped me very well :

My apologies if my english is not very good.
Thanks.
