pre tension of bolts Non linear sub cases

Mani kumar_21615

Hi,

 

   I am trying to do non linear simulation in this i have created a 2 load steps as shown below,

 

Load step 1:            Pre tension of Bolt----------Non linear analysis

Load step 2:           external load          ----------Non linear analysis

 

I have called 'Load step 1' in 'load step 2' using STATSUB(PRETENS) and CNTNLSUB 

 

I have followed this ' OS-T:1390 Pretensioned Bolt analysis of an IC Engine Cylinder Head,Gasket and Engine Block System'

 

It throws an error,

 

 Please solve this issue....

You're using statsub PRELOAD.

You need to use statsub PRETENS.
