Hello,

I am trying to simulate the detonation of an explosive charge in order to obtain the graph p(t):pressure(time). But, the results obtained from radioss code are very different from the ones resulted from Autodyn or experiments.

So, now we are trying to rewrite the user material law (for the law JWL used for the explosive) in Fortran. But, being new in fortran, I really don't know how could i make the subroutine for the engine: 'sigeps.f'.

If somebody could help me, I will be thankful.

    not your exact answer but if i were you i would check ALE tutorials (arbitrary lagrangian eulerian). for explosion it is the best solution as i know.
