Continue one loadcase in another file to save time

HI,

 

I have a query regarding multiple runs with 2 subcase (optistruct: LGDSP=1).

For Example:

 

I have around 10 different Loading conditions all in different files, say...

File1.fem - Lc1 and Lc2,

File2.fem - Lc1 and Lc3,

File3.fem - Lc1 and Lc4,

......

File10.fem - Lc1 and Lc10.

 

Here each file has same mesh, same numbering of nodes, etc. Each file has Lc1 as a common boundary condition.

The difference between each file is the second loadcase (different boundary condition). Second loadcase has CNTNLSUB = YES

 

Hence, currently I have to give all 10 runs with all loadcase. The tragedy is that the 1st loadcase is same for all, however It will calculate the stiffness matrix for each and every run (a waste of time).

 

Is there a way where I can create a separate (master) file for LC1 and run it only once.

Then use (continue) those results in separate files (i.e. with 10 different loadcases).

 

This will reduce the run time a lot.

 

Kindly help.

 

Thanks & Regards,

Ruchik Tank

    Hi Ruchik,

     

    Hope you are doing great.

     

    Yes, you can solve the LC1 with Restart files written to this subcase.

     

    You can then use these Restart files to run Job 1 to Job 10 by solving for only Load Case 2 in each Job.

     

    Thanks
