i want to mesh a large volume of fuel inside a tank. which kind of element should i use? is there any special way to mesh the fluid component? Thanks
Hi Toan,
It is based on your modelling approach. For ALE approach, you can use solid elements and assign /MAT/LAW37 (for air and water).
Another approach is to model using SPH elements.
For ALE approach, there are examples in our Help Menu.
