ABAQUS Contact problem using SPH Method

ABAQUS Contact problem using SPH Method

ABAQUS Contact problem using SPH Method

(OP)
hello

I have been facing a Problem in obtaining a water Impact on a material box using sph method. i do not receive any error during Simulation but there is a warning message about
"Some nodes involved in general contact have penetrated their
tracked faces by more than 50.000 percent of the typical element
dimension in the general contact domain, 4.5263. Please check the
node set "InfoNodeDeepPenetFirst" in Abaqus/Viewer for more
information. Please make sure that these nodes and their
contacting faces have sufficient mass to allow the code to
calculate realistic contact penalties for enforcing the contact
constraint."

Simulation does not give anz splash instead the water ball passes through the material.

How do i solve it?

Below I give the Input file
