Hello,<\/p>\n

I am a beginner to LS-DYNA. I would like to simulate the wake around a ship moving with a constant velocity by using the ALE method with penalty coupling. I have the following queires to begin with.<\/p>\n

1. Is ALE method recommended for such simulations involving larger time durations?<\/p>\n

2. To begin with a simple numerical simulation, I start with a partially submerged cylinder. Would ALE solver be able to capture the effects of viscous drag and boundary layers?<\/p>\n

3. Are there some recommendations to model the water around a floating body (material properties and equations of state) which would particularly suit this simulation?<\/p>\n

I am working on my master’s thesis regarding ship collisions. I would like to use the ALE method to investigate the collision phenomenon along with the Fluid-Structure Interaction. Is it possible to use a different solver such as the ICFD solver for the initial phase of the ship motion (generating the wake field around the moving ship) and then switch to the ALE solver for the collision simulation.<\/p>\n

Thanks & Regards<\/p>\n
