I need to define several combinations in MAXIMA as exemplified below. Envelope results are stored in the database under LC 2121 (max N) / 2122 (min N). Are results stored for both comb 1 and comb 2 in LC 2121 / 2122 when “base” for both combinations are the same? If not, how can I store results for multiple COMB under the same LC?

COMB 1 base 2100

Hello,

the result load cases must have different number for each combination rule for actions!
In your example you have chosen the semi-automatic load case numbering with BASE number which is defined in record COMB. The BASE number for combination 2 must be different to combination 1. Otherwise only the results of combination 2 are saved in the CDB.

Please change the BASE number in COMB 2 and for the two last SUPP records SUPP COMB 2 → currently combination number 1 is defined in the SUPP records for COMB 2.

For more information please note the explanations in the manual MAXIMA chapter 3.10.2 Definition of the Result Load Case Numbers
