Pressure on plate during blast

Greetings everyone, 

 

I am here to seek some help for one of my simulations. I am trying to set a very simple model of blast in Radioss (constrained plate subjected to an explosion in free air) but the results seem strange. The blast propagation is not what I was expecting and, on top of that, when looking at the results on the plate the pressure stays at 0 during the whole calculation (even though I have displacement and stresses). I would appreciate some tips about blast modelling on Radioss and I attached my current model if someone wants to have a look at it.

 

The unit system used within the model is m/kg/s and I work with law 51 to model everything but the plate which is modeled with a Johnson Cook law .

Thanks in adavnce
