Dear cig-seismo members,

Thanks for your contribution to the SEM software.

However i have a problem when using the SPECFEM2D, the thing is when
calculating SH wave, it seems that the source cannot be set as Moment
tensor type and actually the input arguments for a moment tensor source
includes only Mxx, Mxz, Mzz while Mxy, Myz contribute mainly to the
far-field SH wave.

I'm quite perplexed and wonder if i understand correctly. Could you explain
me more?

Will be very very appreciate if you could reply me :)

Best Regards~
