Thanks Thomas
i do run linear analysis ,Like say i have Load case1 - FX; Load case 2 - Fy; Load case 3 Fz; then i need the conbined load 0.2*Fx+0.3*Fy+0.4*Fz. What i do is go Menu Model/Load/Combine. but i do like this, when i change basic load case data, i need to re-combined them again. you mentioned the case control command subcom. where is it? can you explained more details?

Hi
When you set up the Cases in Femap there are two options, Standard Case or Subcom. If you select SUBCOM you will get i little menu where you can select Subcase factors. Those are basically load combination factors. You will find a very simple example below. It combines Selfweight with either Live 1 (factor 1.1) or Live 2 (factor 1.2). Three loads and two combined cases (subcom's)
Another completely different approach would be to use the Program File and record your actions. Then you, at least, won't have to push the same buttons again and agian.

SUBCASE 1
SUBTITLE = Self weight
LOAD = 1
SUBCASE 20
SUBTITLE = Live 1
LOAD = 20
SUBCASE 21
SUBTITLE = Live 2
LOAD = 21
SUBCOM 50
SUBTITLE = COMB 1
SUBSEQ = 1.,1.1,0.
SUBCOM 51
SUBTITLE = COMB 2
SUBSEQ = 1.,0.,1.2
