i am not very practical with opensees, I need to model a cylindrical steel tank.
I wanted to know if someone with more experience could give me some advice/example about it.
I must outline the tank with a simplified cantilever model.
The liquid mass will be divided into two masses, an impulsive and the other convective.
I do not know which properties give to the cantilever and how to outline the springs that give the two masses, the impulsive and convective efect
