I am running the StirFromFile unit to simulate the high Mach turbulence, I want to add the Particle later after the simulation is steady, but I did’t see a runtime parameter for this purpose. The guide have mentioned the “Particles_Addnew” function, but it was called by the “ParticlesInitialization” Unit when the simulation begins, Is there anyway to add particles to the simulation in the middle time? I want to do this because I want add 100 millions particles to the simulation, it will make the simulation slow down, So I want to add the particles finally to see the property.<br>
<br>
Any suggestions are welcomed! <br>
<br>
Best wishes! Everyone! <br>
