Hi, 

I am analyzing a pipe with flanged ends and I am using one spider to connect all the bolt holes. I am applying several reaction forces from a connecting piece of equipment then adding those loads with LoadADD card. I can add one moment, but then when activating other load collectors for the point loads the node can be selected (turns orange), but i create the point load on the node it turns grey and nothing happens. Can you apply multiple loads to a single spider node?

    Hi

    I am assuming you are creating the loading for OptiStruct model.

    There is not limitation to creating different loading direction on same node and combine them with LOADADD.

     

    It can be some related to the graphics. 

    Did you try to update your graphic card driver?

     

    Regards
