RADIOSS or LS-Dyna?

RADIOSS or LS-Dyna?

RADIOSS or LS-Dyna?

(OP)
Hi,
I am a new comer in Dynamics. In my lab, we are using mainly Abaqus Standard and Explicit and sometimes ANSYS. We are advanced users of ABAQUS (UMAT,VUMAT, Python scripts). For dynamical problems where fluid/structure interaction are needed, I'd like to have your opinions about RADIOSS (Hyperworks) and LS-Dyna. I am testing LS dyna now and will test soon Radioss.
According to your experience, what is the BEST software between those two softwares, to perform dynamic impact simulation, dynamic fracture and manage fluid/structure contact? Which one offers the best ergonomy for users?
Thks for your help.
