Hello there, I'm trying to run a simulation with RADIOSS 2017, but I keep getting the errors shown in the screenshot attached below. Can anyone help me? I've also attached the .rad file

    Hi @MatBannwa,

     

    The problem was with the definition of master surface on tied interface: it was referring to the component which also had slave nodes. Basically, it was defined as self-impacting contact interface. A tied interface (TYPE2) can be used to connect a fine mesh of Lagrangian elements to a coarse mesh or two different kinds of meshes (for example, spring to shell contacts). So you need to pick another component as a master surface- I defined contact surface on the bottom of honeycomb. There was no search distance (dsearch) and Ignore should be set to 1 on the tied interface card.

     

    There was also error with 'EN AW 7075' material definition: it did not have function fct_ID referred. So I created some fictional function, just to be able to run the model.
