Error #720

Recommended Posts

 There were 3 error messages during input processing.

  The first message is repeated below:

 

  *** ERROR # 720 ***

  Invalid static SUBCASE that has no load or enforced displacement.

      subcase id = 1

 

 

************************************************************************

 

 ==== End of solver screen output ==== 

 

This error appears when I add a secondary force or constraint onto multiple sections of my model. Any help is appreciated.

HI luongo1,


 


Make sure when you add new loads, constraints are under right load collectors.


 


For instance, you cannot have constraints in Force load collector and the same is used in loadstep for load.

I think the problem is that i'm using basic FEA and hyperworks keeps creating it's own load collectors and referencing those collectors. This happens when I make a load step in basic FEA. If i right click them on card edit, it'll say 'No card assigned to the entity for the current user profile'.

Hi,


 


I have got your model.


 


You have four loadsteps. Each loadstep either has an SPC or FORCE.


 


This is not the right way. You need a force and SPC on one loadstep. Please make these changes and re-run the analysis.
