Hi,

Could anyone explain what does the "number of time discrete levels" mean?

Thanks.

Best
Lakshmi.

This shows the number of previous time steps that the solver will keep. if you want to have a variable like prev(ux,2) this means that you need to keep variables for two past time steps (level should be set to 3).

by default it is set to be 2. This means that it goes and saves the previous time only (e.g. works for prev(ux,1)).
