The SQP method is slow to calculate 6000 cylindrical particles on Linux systems

Hello, everyone!
I use the method of initial accumulation of particles to calculate 6000 cylindrical particles, in the linux system is very slow to calculate, please teachers to help me see, which is the parameter setting problem ? Or does the initial accumulation of particles lead to slow calculation speed ? Thank you！

I haven’t looked at your file yet, but you should expect that simulating 6000 SQP particles will be slow. SQP is significantly slower than DEM. If you can run on multiple CPUs (using DMP or SMP) that will help. I’ll take a look at your case when I get a chance.
