SPH modelling with LS-Dyna

Dear all,

I'm using LS-Dyna and I would like to model the interaction between a viscous fluid  and metallic substrates.

If everything is working in 3D, it's not the same with the 2D...

Indeed I've used each contact algorithm (I think) in LS-Dyna and each time the contact between my 2D elements and the sph is not initiated.

Does anyone has an explanation to this curious problem ?

Maybe I'm not using the good contact setting.

Or contact between sph and 2D elements is not available in LS-Dyna.

Can you help me ? 

Thanks in advance

 Best regards

 David
