[CIG-SEISMO] Problem with source

[GulaAK at ipgg.sbras.ru]

Hello!

I have just downloaded last version of SPECFEM3D_Cartesian, 
in new version you added new type of source: FORCESOLUTION.
Thereby I have the following questions, I need to use exploding point source (expansion center).
How I can get it, should I use CMTSOLUTION for this purpose or FORCESOLUTION?
How I can get several point sources?

Best regards,
Aleksey Gula
