Is it possible to simulate in hypermesh with more than 1 Load Collector, where each load collector is associated with different forces? In other words, I'll have several forces in the model. If it's possible, can you tell me how?

    It depends on the solver interface.
    In OptiStruct you can create a load collector with the LOADADD card to collect several load collectors to include in a load step.

    My solver is the OptiStruct. So, how can i do it?

    1. create a new load collector
    2. change the card image to LOADADD (see above)
    3. change LOAD_Num_set to the number of load collectors you want to include
    4. select the load collectors (table button for more than one, then the table below will open)
    5. optional: change the scale factors

    This is if you want the different loads in the same load step. You could also create multiple load steps with different loads.

    If i want to create multiple load steps with differente loads is the same process?

     

    I have this error when i run the simulation. Any suggestion?

    You can't add a load collector to itself. The loadadd load collector you are showing has an id of 2 and you are also calling load collector id 2 within that load collector. Remove the load collector 2 from the list.

    Yes, just create multiple load steps and reference the loadadd card or a single load collector as desired.
