Hello all,
I have an anisotropic layer sandwiched between two fluid layers.
I can fire 1 source from the elastic/anisotropic layer no problem with a pressure source (source_type = 1).
But if I have 3 pressure sources, one in each of the fluid regions, one in the anisotropic region, the source in the anisotropic region doesn’t fire.
If I change only the source in the anistropic region to an isotropic moment tensor (source_type=2), then all sources fire.
Unfortunately, I am only allowed to include one image, so below is a trace recorded by a receiver directly above the sources, validating this in the data. The arrow points to the signal created when the source in the anisotropic region is a moment tensor, but missing when it is defined as a pressure source. The seismometers are recording pressure.
Any ideas as to what might cause this?
Best,
Jami
