How can I use renormalized SPH formulation in Abaqus?

12 December 2014 1 5K Report

LS-Dyna has re-normalized SPH formulation. Is there a similar formulation in Abaqus?

Under *Section Controls keyword in the second data line for the sixth parameter, enter '1' (without quotes) to activate NSPH method.
