Good morning,

I am currently working on cyclotron simulations using the OPAL 2021 build. I have previously been running in carboncycl mode and everything has performed as I expected and in accordance with the manual. However I recently started trying bandrf mode with a 3D field and I believe I am misunderstanding how to run this with multiple cores. When using carboncycl mode it seamlessly engages as many of my cores as I ask it to, but when I do a similar procedure with the 3D field it seems to use at most one core, albeit again running the simulation with results that make sense to me.

I'd appreciate any advice you have on what I may be doing incorrectly here as I have not been able to find a solution in the code or manual at this point. 

Cheers,
Jarrett Moon
