Modeling effective pressure hermeticity

      Hello all,

      I am shooting a laser beam via radiation on a weld joint and correspondingly trying to understand the gas pressure in the air cavity and it's effect on the neighboring solder material.

      If you include a gap (including porous media) then air will leak. Modelling the gap will require far too much mesh, so isn't a good idea. Do you know how much air is leaking?

      we do not, and that is what we would like to try to characterize. Is there a more preferred approach to emulate an imperfect seal on a perfect model geometry to more closely mimic reality?

      In most cases we assume zero leakage. If you run like that what's the maximum pressure you see in the air space?
