ALE - Simple Slosh Case

Crashphys

Hi all, just trying to mess around with ALE a little bit to get a better understanding. I modeled a simple cubic box filled with water and experiencing an inertial load of 0.3 g and gravity. The corners of the bottom of the box are restricted in the 123 directions. I have the results according to the .gif attached, which appears to be... flickering? Am I getting correct results and interpreting them incorrectly?

Thanks in advance.

Hi aymanalsukhon

Try applying hydrostatic pressure to it. If you are using HW version 18 than you can achieve this by using /INIGRAV/ control card. I hope after applying hydrostatic pressure it will behave properly.

Hi,

Unfortunately I am on the 2017 version, which to my knowledge does not have that card. Can you suggest an alternative to it for the lower version?

Thanks

Hi,

You can use .tcl script for lower version for generation hydrostatic pressure. I think that can be available with your Altair support person.

Thank you, I will check with them and report back.
