Hello all,

I'm trying to use flowengine to introduce fluid into the system. However,  I dont know how to simulate a sinusoidal-shaped pressure condition at the top boundary of the packing  (eg p=Asin(t/T)cos(x/L)), refer to this in paper [1] . Should I  use the boundaryPressure and boundaryXPos of flowengine?  Or should I use another engine?

Thank you for any suggestions.

Deng
