I am running a rainfall plus reservoir water fluctuation induced landslide model using a Richards Mechanics process. During model preparation, I am facing a few difficulties and have few queries.
1. Setting suction pressure cut-off.
Is it possible to set maximum suction pressure cut-off in OGS as given in the following figure?
2. Boiling water table.
If initial pore water distribution is defined and the model is run to get the equilibrated water table. The water table boils and then settles afterwards. This could be avoided by using a large initial time step, but is there any other way to prevent groundwater from boiling?
I have prepared a simple test case for that:BoilingGroundwater.zip (171.0 KB)
3. Linear type density for AqueousLiquid phase
Recently updated benchmarks have a linear type density parameter for the liquid phase. What does that mean? Actually, this property tends to stop boiling groundwater but how to find slope and reference condition for a particular case?
