I have a model with 12 static load cases (tank with compartments). Now when I add equivalent lateral force cases with definition of additional eccentricities in +/- X/Y directions, using Newmark combinations, I end up with 42 load cases. Naturally yhis generates a huge number of combinations. What would you advise in such a scenario to limit the number of combinations. I have tried generating automatic simplified combinations (all bars) but it does not seem to help much.

I am afraid you have to look at Relations and simplify them to generate smaller number of combinations.
Hint: use only seismic CQC combinations instead CQC + simple seismic cases or vice versa.
The limit can be changed here:
I am still grappling with the groups and relations tabs in generating combinations. For example I have unchecked the simplified seismic cases on the "cases" tab to make them inactive, but they still appear on the "Groups" and "Relations" tab

OK, but they will not be used
