Bolt preload and multiple subcases

Hello Community

 

Which seetings a have to applie for a simulation with bolt preload and multiple subcases?

I have in subcase 1 only the bolt preload, in subcase 2, 3, 4, .... the bolt preload and different forces.

 

Current state:

- Calculate subacse 1 (bolt preload)

- Calcualte subcase 2 forces

- Calcualte bolt preload

- Calcualte subcase 3 forces

- Calcualte bolt preload

- Calcualte subcase 4 forces

.....

 

Ideal state:

- Calculate subacse 1 (bolt preload)

- Calcualte subcase 2 forces

- Calcualte subcase 3 forces

- Calcualte subcase 4 forces

....

 

 

Thanks and best Regards

Re: Bolt preload and multiple subcases

Is the SID of the bolt preload the same in all 3 subcases? If it is, the preload should not be recomputed in subcases 2 & 3.

 

Alternatively, if you put the preload in the global case, it should only be calculated once.
