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.
