load combinations including bolt preload.

Hi,

I want to calculate many combinations of loads:

Basic loads:
weight
bolt preload
Lat
Long
Vert

Combinations:

lat+0.3long+0.3vert+weight+bolt \ -0.3lat+long+0.3vert+weight+bolt
lat-0.3long+0.3vert+weight+bolt \ -0.3lat-long+0.3vert+weight+bolt
lat-0.3long-0.3vert+weight+bolt \ -0.3lat-long-0.3vert+weight+bolt
-lat+0.3long+0.3vert+weight+bolt \ -0.3lat+long-0.3vert+weight+bolt
-lat-0.3long+0.3vert+weight+bolt \ 0.3lat+0.3long+vert+weight+bolt
-lat-0.3long-0.3vert+weight+bolt \ 0.3lat-0.3long+vert+weight+bolt
lat+0.3long-0.3vert+weight+bolt \ 0.3lat-0.3long-vert+weight+bolt
-lat+0.3long-0.3vert+weight+bolt \ 0.3lat+0.3long-vert+weight+bolt
0.3lat+long+0.3vert+weight+bolt \ -0.3lat+0.3long+vert+weight+bolt
0.3lat-long+0.3vert+weight+bolt \ -0.3lat-0.3long+vert+weight+bolt
0.3lat-long-0.3vert+weight+bolt \ -0.3lat-0.3long-vert+weight+bolt
0.3lat+long-0.3vert+weight+bolt \ -0.3lat+0.3long-vert+weight+bolt
:eek:

I have used the Results, RMB ; Combined load cases tool to do this but it is really tedious and not user friendly.

How about improving it like the Subcase Association Manager, with the addition of coefficients?

Has anybody another suggestion for quick way of doing combinations?

yours sincerely,

This could be automated by a journal. Record a journal while you do one of the combinations. Then edit the journal and repeat for the other combinations.

Hi Jim,

I tried but those instructions are not recorded in the journal. Only yhe opening of the menu was recorded.

Cyril,
I was referring to the Combination type Results Manipulation tool (Tools --> Results --> Results Manipulation). This is expression based and allows you to combine results across subcases/solutions. It is recorded in a journal.
