Dear all,
I am trying to build a subsurface model containing a void space (cavity). I have tried to use the “block” command to add a rectangular cavity and set Vs = 0 and a very low density (1.2 kg/m3), but this makes my simulation crashing. I have also tried with Vs, Vp, density, Qs and Qp equal to -999, but this also doesn’t work. How should I proceed? Is there an alternative command to “block” that I should use?
Thanks in advance
