Hi, I found a bug (?), the model calculates normally and the explosion happens. But when I change for example the radius of my TNT cylinder, the reaction just does not happen, the time step goes in a strip (and no, the detonation point is where it should be, I changed it).  Although for example the extrude of my TNT can be changed, everything works.
The same way it happened by accident and when changing other parameters.
Screenshots: 1-3 is a working file, 4-6 reduced the radius of TNT from 31.5 to 20mm
Pls help me.

Hi, is the euler domain corrected to all bodies ? in second design change, is the detonation inside or whith in the proxy to the body ?, 

cheers, ram

The detonation point is in the bottom-middle of the cylinder, and the Euler domain is calculated according to the height of the cylinder, i.e., changing the diameter of the explosive does not affect these two parameters.
