I was using some material properties. when cutting tool is going to cut the rock, the tool is not cutting and tool position is changing and moving on it.
how to solve this simulation
Hi,
You can Perform this Analysis in Radioss or In Motion Solve .It depends on what is the objective of cutting. If it is to see the forces on the tool, heat generation etc then RADIOSS. Please tell me your Objective of Analysis.

depending on what you want to do, you could use SPH to represent your rock and a rigid body for your tool.
Firstly, thank you for information.
So how is the ideal number of particle determined in models with SPH? /profile/97129-adriano-a-koga/?do=hovercard' data-mentionid='97129' href='<___base_url___>/profile/97129-adriano-a-koga/' rel=''>@Adriano A. Koga
Thank you.
just like regular FEA models, i would say this depends on a few factors, and a convergence analysis would be a nice approach. I mean, start with a small particle numbers, then run a new model with more particles, and so on, and then compare your results. Of course it depends on what you're trying to compute.
Just as an example, there is an example model in this topic, create by @Rodrigo Merigo.

Thanks for the previous information Mr. Adriano. @Adriano A. Koga @Adriano Koga
I am planning to prepare a model that includes SPH. However, I am new to this. I could not find much information.
Can we say that as the number of particles increases, the results get closer to a certain value? And after a certain number of particles, increasing the particle number wont effect the simulation results? (which is the case for mesh convergence in FEM analyses)
Are there any tutorials, academic paper etc. that you know about the subject and that I can use as a reference?
Hi @Ovunc2
Attached is a model created by Rodrigo Merigo that performs a machining process using SPH.
For creating your SPH you need to go to Mesh >>Create >>SPH
take a look at Radioss documentation for more details on SPH and the example in the documentation, attached.
Thank you very much Mr. Adriano @Adriano Koga .
