Guys, I got a clue to the cause of the particles scattering. I decided to create a new discussion, sorry.

Look.

When I solve the problem in time for 0.0001 sec and turn off mass scaling then the calculation passes. Also, I don't have to add the CONTROL card

 

 

If I make a task for 1 second and turn on mass scaling and define a timestep then the particles fly apart when the drill and particles come into contact

In addition, I have to connect the CONTROL card with a snippet in order to increase the mass

otherwise I get an error:

Colleagues, tell me why this is happening?

Hi,

 

I think Ram helped you with this query here: SPH particles fly apart on contact with the drill (ansys.com)

Excuse me sir. This is a relatively new feature. Tell me how to include it in the LS-Dyna WB (ACT)?
