ADINA multiphysics
ADINA multiphysics
(OP)
Sirs:
I am preparing the seismic design criteria of a very
large bottom supported tank.Due to the size and importance of the tank I am thinking to use a coupled FE model that
incorporates the tank and its contents.With such a model
the hidrodynamic interaction I hope will be best accounted than
using a first "sloshing mode" as in the API 650.
Does anybody have experience on using ADINA for this?
Best regards,Capablanca

RE: ADINA multiphysics
I find it far easier to use a specific formulated program rather than meeting the requirements for a successful solution using the above "hogs". The NISEE Software Library has programs written by Nash that are designed to include a fluid mass matrix.
At http://www.volcano.net/~d.citerley my references 10, 12, 13 and 15 demonstrate just this class of problem. Notice, I have been talking about including a mass matrix and not considering slosh modes. Slosh modes generally do not produce significant pressures compared to seismic effects that correspond to axisymmetric (n=0) and lateral (n=1)fourier harmonics..
