Description:
Detailed description of the creation of a model in LS-PREPOST4.3 for LS-DYNA
The model will consist of 3 parts: Water, air and the ball. Water and air are modeled by the Eulerian method. The ball is modelled by the Lagrangian method. The ball will throw into the water at an angle of 20 degrees at a speed of 3.1 m/s

Hello, I met a problem--*** Warning 10302 (KEY+302) CHECKING MATERIAL INPUT Part ID= 2 The default hourglass properties of the following ALE part are being modified to avoid unnecessary application of hourglass forces. Resetting coefficient qm=1.0e-6. PART ID 2 with MATERIAL ID 2 and EOS ID 2 This is PART 2 in the order of input. what's the meaning of it? could i brother you to help me to explain it? thanks

I have a question about the average pressure figure. Is it reasonable that the average output pressure on the ball comes to zero rapidly after its peak? In my opinion, it should go down lightly with fluctuation after the peak and come to a steady level.

Peaks are associated with grid dependence. There is a constant pressure from 10 to 50 msec

Thanks for your reply. I'm still confused about the output graph. In the graph of output pressure between fluid and ball at about 3:05 in the video, why the average pressure from 2 to 5 msec contains zero value? Is the zero value reasonable for the simulation? What causes the zero value? Thanks again!

These are the features of the dynamic analysis program. Zero values are not correct. This is easily eliminated by the introduction of filters. I needed to make a filter here and smooth the graph, then there would be no zero values

What kind of boundary conditions is applied here?

Boundary conditions using Automatic Euler boundary condition in the card *control_ale

I have a question, I followed this and for some reason it did not work. Would there be a way for you to send me a .K or something so I could compare?
