Dear Team,
I would like to confirm how the source term is applied in the current configuration of specfem2D, specifically for a PSV problem.
We are using source_type = 1 (elastic force or acoustic pressure), and the parameter anglesource is set to 0.0.
In this case, I would like to know:
- Is the force applied to the Vx or Vz component during the update step?
- In the case of an SH problem, would the source be applied to the Ux or Uz component instead?
- Does
anglesource = 0.0 correspond to a force in the x-direction?
Thank you very much for your help in clarifying this.
Best regards,
