Using results from the previous time step

Is there any way to use the results of the previous time step when using the time dependent solver? I'm solving for saturation and want to compare the level of saturation with the previous saturation, for example if Sat(k-1) > Sat(k) use the value of Sat(k-1) in further calculations. I know that you can use the prev() operator with the time discrete solver but when I use this solver it seems to freeze my computer.

Dear Michelle,
probably a search on hysteresis modeling in COMSOL can help you with this.
Typically you can use a PDE which stores whether you are in imbibition or in drainage.
Alternatively you may search on imbibition - drainage, but that is much less common I assume.
Best regards,
Frank
