Static condensation with multiple load cases

Hi

 

I want to apply the static condensation on a problem with multiple load cases. 

In manual, 'p2gsub' keyword exists but there is no detail explanation about that. 

Please, let me know the process of static condensation with multiple load cases. (the cases of same SPC and different SPC)

I hope there is a smart way rather than the separation of model same as the number of load cases.

    I think it should be possible as it has to with the elements, provided the same matrix is used for both cases

    This content exists in manual. But I can't find 'p2gsub' in the control cards.

    Hi,

     

    Unfortunately, this is not available through GUI.

     

    Please add the same on solver file by editing in any text editor or using Bulk_Unsupported_Cards

    Oh, I will try this. 

    And, you said 'I think it should be possible as it has to with the elements, provided the same matrix is used for both cases'

    Is this meaning that the static condensation with multiple load cases is only possible in the same SPC load cases?

    I think so, because you need another set of SPCs for a different one.
