I trying to calculate the force generated on a wall due to the sloshing of water in a rectangular tank
The problem is that the force is not changing by increasing the length of the tank
What should I do ? Or What is the right way to do it ?July 12, 2021 at 12:05 pmKarthik RAdministratorHello Some high-level thoughts -
Is your simulation converging energy time-step? Are you able to obtain an animation of the interface sharp over time and is this different when you change the length of your domain?
You are modeling this as laminar. Is the flow really laminar if there is sloshing?
Your time-step size seems a bit large. Have you checked your CFL number based on the minimum grid size and the velocity scales of your problem?
How are you modeling the tank sloshing? Are you changing the gravity vector with time?

July 13, 2021 at 12:11 pmKarthik RAdministratorHello,
You can simply set up a force monitor as follows:
Solution -> Reports -> Definitions -> New -> Force Report -> Force
Make sure to pick the direction of the force vector appropriately. Select the walls under face zones.
