User Defined Automatic Load Combinations

[Babak.moussavian]

There are 7 different live loads in the attached model, load case 4 through 10.

I have created a user defined load combination based on Eurocode as per 6.10 C (GEO) which is attached.

STR-GEO Sett C.rgl contains user defined subnature.

I want to make following load combinations:

Combination of Load Cases 4 and 5:

• Load cases 4 and 5 can be combined with load cases 7 or 8 (or both, or none).

         Load cases 4 and 5 cannot be combined with each other (they cannot act simultaneously).

Combination of Load Cases 9 and 10:

• Load cases 9 and 10 can be combined with load cases 7, 8, or 6 (or any combination of these, including none).

         Load cases 9 and 10 cannot be combined with each other (they cannot act simultaneously).

I have made 4 groups for live loads shown below:

Furthermore, I have defined following relationships between groups, but I see that live loads 4 or 5 are combined with live loads 9 and 10!

I would appreciate if someone can help me to create all possible valid combinations based on the defined groups and constraints.

Hi @Babak.moussavian!

Check if this rule can solve your problem:

I first focused on the groups that you don't want to combine (or EXCL), then just put the rest as "or incl".

Hi @CaioSaporito!
Yes, it solved the issue. I could make 83 combinations as my preference.
Thanks for your help.
