Dear Adrian

Thanks for your reply, but I still haven’t solved him. Do you mean I should compile in parallel instead of “make”? What should I type then, how can I solve it like this?

hfx123@ubuntu:~/olb-1.6r0/examples/particles/bifurcation3d/eulerLagrange$ mpicxx -O3 -o bifurcation3d bifurcation3d.cpp -I/home/hfx123/olb-1.6r0/src -std=c++17

I’m looking at “run.sh” and I know that if I compile successfully, I should type”mpirun -np 8 ./bifurcation3d 19 1000″.I hope you can tell me how to compile and run it, because I really don’t know much about parallelism!

Best,
