I just doing a simulation for liquefaction on gentle relief slope with the dynamic load is 50s which consist 0.01s each data.
I use PM4Sand for the constitutive model applied on the sand layer also HS Small for the clay.
Currently I set the Max steps of 150 and automatically set for the sub step.
The problem I faced is the calculation always stuck at 13s or on step 37 to 40. There are no error messages comes up and the calculation wasn't stop. It already took 4 days and it still stucks on that point.
What could be the reason for it? And how to solve it?
Hi. This sounds a very specific problem that results in probably some internal checking issue that gets stuck.
Sometimes it can help to change the mesh in the problem area. You can see this eg in the intermediate results if there is some anomaly in results as excess pore pressures or displacements.
