Hi sir,

I am very new to Optistruct and tried doing multistep analysis -like carrying the 1st step result to next consecutive steps,

but results does't seem to carry forward the previous step results.

solver type used - generic type, and also tried doing in NLstatic.

 

can you suggest some useful tips,

Thanks in advance.

    Hi,

     

    Did you use CNTNLSUB to carry results from previous load steps?

     

    Can you share the model files please?

     

    Please use the file transfer link in my signature to share the model file

    Hi prakash, 

    I haven't tried using CNTNLSUB,  but will try adding that option. 

    Initially to understand the tools in optistuct,  i have considered a simple cantilever beam and will try sharing the file as soon as possible. 

     

    Thanks,
