Hello,

I have been using your ChaNGa code to calculate forces between the particles.

When it comes to calculating forces there seems to be an issue. Particle to node (using nodeBucketForce in gravity.h) is not being calculated to the correct value. I am not being able to figure out why this is so.

We printed out the tree and verified that it is correct. We also verified the Centre of Mass for each of the node to be correct.

Can anyone give me helpful pointers where I might be going wrong?

Thanks,

Shad Kirmani
