Hello everybody
Im starting simulation and analysis of new student project,Projectile moving inside barrel.
I need to your helps for making a topic that consist all sides of this project for me and other users that need fast guide in future.
i try to make it some parts that everyone can learn it step by step.
Tanks a lot
1-at first how can i mesh it?

what exactly do you want to show with that simulation? A moving mesh is not necessary as you can't model the exact movement of the bullet so I'd just go for a hybrid unstructured mesh and apply the traveling speed of the bullet as the flow velocity.

hello
tanks for your rapid response.
i want to simulate moving a bullet in barrel and its exiting of barrel.
at first how can i mesh it for moving bullet in barrel?(at all how we can run the bullet in barrel?)
then where i should put initial pressure or velocity?
TNX a Lot

meshing of this problem is not so important,
the setup for dynamic mesh, boundry condition and the parameteres are important for this simulation,
at the first try
you can mesh the barrel by quad and interval size of 1
and you can use inviscid model because its a high velocity problem and boundry layer is not important
