Hello Peter, 


   ? would love to thank you for your valuable help with the barrel analysis, we have got a good progress so far , But the current problem is that i couldn't accelerate the projectile as it had to be . In real life conditions, the projectile has 1200 m/svelocity , when it has just rejected from the barrel but now we got just 430 m/s aprox. we have increase the explosive amount in order to accelerate it . But now it occurs ''energy error too large Error'' . We have incerase the reference energy cycle, it doesnt solve the problem still working on it, any suggestion ??
