Blast in explicit dynamic – zero results

      Hi everyone,


       


      I wonder why I've got "zero" results in my first very simple blast fun ?


       


      Does anyone prompted ?


       


      Thanks in advance

      Where was the detonation point being set off?

      Look at the DET_INIT_TIME and ALPHA as specified in the link above.


      Note that detonation point is only valid in solid geometry. Also, turn off the instantaneous burn option.


      What shock material model are you using and how do your analysis settings look like?

      Hi,  


      I asked University IT for the access to Anys help but it takes time. 


      Detonation point is beneath of one liter (1 dm3) of Ansys's TNT represented by solid box geometry. Instantaneous burn option was set "no".
