Sloshing simulation with ALE SPH

RomainMegret

Hello everybody

I'm currently trying to do a sloshing simulation on Radioss using SPH and ALE but i have few questions.

First of all, does it exist any test case or simulation already done that i can reproduce?

Then I have more technical questions :

• How could I impose a rolling motion to my tank on radioss?
• How to set up the case in order to observe the impact of the particles on the rigid walls (made of elastomers)

During my researchs i found this video :

#Radioss | Altair Radioss를 이용한 Tank sloshing 해석 (FSI)

but there's not that much details.

Thanks in advance

Hi,

There are two examples that might help you with tank sloshing:

Hello,

Thanks for your answer. I therefore started to do some simulations but i have some trouble understanding all the parameters of the type7 interface, and what could be their impact on the simulation.

Do you have any documentation on that? thanks in advance
