Dear Jan,

I believe we should focus on whether the particle simulation can run in parallel. You can even set the particle time step very small. First, you can run it in serial mode, and then switch to parallel mode to see the issue that has been bothering me.

After you run the fluid simulation without particles for the first time, in serial mode, it will directly read the fluid results fluidSolution obtained from the serial run. In parallel mode, it will directly read the fluid results fluidSolution obtained from the parallel run, so it will not simulate the fluid again.

const T physConvergeTime = 0.1 * charPhysT;                   // time until until statistics sampling in seconds
const T physStatisticsTime = 0.1 * charPhysT;                  // statistics sampling time in seconds
const T particleMaxPhysT = 0.1 * charPhysT;

Best regards,
