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,

    You're using statsub PRELOAD.

    You need to use statsub PRETENS.
