I want a source that explains how SPH deals with friction modeling example Coulomb friction. This can be for either Abaqus or LS-Dyna or any other software that explains how they can detect contact between two solid bodies and account for friction.
I am interested to your question (similar to my case).and will explain in detail soon. Bit hurry for this time, please consult me.
A good article on this subjet is :
Solid friction at high sliding velocities: an explicit 3D dynamical SPH approach
it present realistic 3D numerical simulations of elastic bodies sliding
in a regime of velocities ranging from meters to tens of meters per second using SPH method.

I want to simulate multi-pass moving heat source using DFLUX. I understand that I should use for loop but couldn't get to work, so is there any example or similar case to it?

I have a subroutine DFLUX and I want to make the FLUX(1) to move so I must change COORDS (1) so should I make a loop and change time from zero to TIME(2) or what should I do?
