SPH formulation

Recommended Posts

Hello

I want to formulate Tube and Liquid Interaction.

- Which Contact type can be used?   I used Type 7. Is it correct? for this, How to define parameter like Istf , STFAC, Gapmin etc etc.

Want to simulate effect of tube formulation from cylinder on inside liquid? Which boundry condition can be used?

Hi Harsh,

We were looking on your model. Based on the loading conditions provided the simulation is happening correctly. Can you please elaborate more on your project?.

Type 7 contact is correct. You can try with Istf=4 and provide a small Gapmin.

Hi George,

I am working on Toothpaste tube forming process.

there are two cases.

1. I want to simulate tube formation process from a cylinder. I want to check difference between volume of cylinder and volume of tube (Deformed shape of cylinder after process)

I am done with this. Please refer attached video. (Cylinder and tube is empty)

 

2. Now, I want to fill water in cylinder and repeat tube formation process. i want to check water displacement when cylinder get convert into tube.

cylinder is closed from bottom and later on sealed on top by two plates.

Hii

When i open the results of the above model in hyperview, SPH particles looks very differnetaly. Can u tell me why is it so?fea.thumb.PNG.9a981aa18c4cac6b44f7178ccba84828.PNG

Hi,

Can you include /ANIM/VERS/44 keyword in engine file and try running?.

If the issue persist please share this model file.
