What support should be acting on base of tank in a 3D tank sloshing under earthquake.
I would like some help regarding an attempt at simulating the sloshing of a 3D tank which contains liquid.
I use ANSYS Fluent to model the fluid parts (VOF, explicit, 2 fluid bodies for water and air) and Transient Structural to model the tank structure (two bodies, lower and upper, so they can be assigned to the corresponding fluid bodies for Data Transfer in System Coupling solver).
Apart from the Standard Earth Gravity, I would like to know what support I need for the base of the tank, so it resembles a tank on the ground, that has also the the freedom to move under a sinusoidal acceleration, attempting to simulate an earthquake.
My guess is the elastic support but I had some issues running with it.
Thanks for any answer and any light shed on the matter.
