Hi,

I have a part which consists of two different material layers. I am trying to form those two different sheets in one forming process. They consist of different materials (e.g. steel and aluminum). I modelled the two layers with two shell components. Is there an option to tie this surfaces together as can be done in FEA modelling as a TIE. Because if i don´t they are actually twisting and not sticking together!

Furthermore there was already a discussion about draping of Composites? Is there already a new release out?

best regards and thanks for your help in advance

    Yes it is possible to run HF forming with multiple blanks. there are two options

    1. Run it a layered blank without any contact between the 2 blank
    2. Run it with Type 2 contacts as welded blank..

    This cannot be run in HF one step. This has to be run in the HF incremental profile
