travel times for multiple sources

[saeedsltm]

Hi, thanks for really helpful and accurate code.

In cases when the initial grid is large, let say 500km (x-y) and 50km (z), computing travel times takes long time for each point of source. So, if we have multiple sources, it needs to run solver first independently. I am wondering to know if there is a capability to define multiple sources and run the solver just one time to make a list of travel times according to each source?

Regards
