Hi all,

 I have developed a viso-hyperelastic material model, and now I am trying to implement it in LS DYNA for which I need to write a sub routine. Since I am developing a subroutine for the first time, I am finding it a bit challenging. I have enough documentation for doing this in ABAQUS but not for LS DYNA. I wanted to know what is the major difference between subroutines written for ABAQUS and LS DYNA? Or is there too much of difference to be even compared? It would be of great help for me if you could answer this question for me. Thank you very much
