Determination of the number of SPH particles

Recommended Posts

Hi, 

 

I work sloshing in the basic rectangular tank with the SPH method. I will try to sloshing in a more complex structure in the future. 

 

I'm new to Radioss solver and SPH method. For this reason, there are a few things I would like to consult with you.

 

  1. It is clear that as the pitch size decreases, the number of particles formed increases. Increased number of particles will also increase accuracy and solution time. How is the ideal number of particles determined? 
  2. I can read contact reaction force and pressure in the model I created. But as with the CFD, is it possible for me to read the fluid pressure?
  3. During sloshing, is the value I read from the pressure gauge on the test apparatus the same as the value I read on the contact surface?

 

Thank you for your help
