Hello Tonmoy,

Thanks for the time taken to reply for my query. 

My aim is to find out what will be the max velocity reached by a particular shape bullet ( material - Stuctural steel) when fired from a cylinder with 90psi. so I've set this up model in explicit dynamics,

My Boundary conditions are,

Pressure 90psi at horizontal direction, standard earth gravity in -Z direction. Analysis time i have given it to 0.05sec.

My aim is to obtain a curve in inverted "V" shape that specifies initial vel, max vel at mid and final vel while bullet drops down. 

 

My question is for an time period of 0.05sec am getting a graph slope line with incresing vel., will i be able to achieve inverted "V" shape if i increase the time step.
