Ok, that's what I thought, but wanted to make certain. Time to explore the results more... Thanks Nathan

Best,

Hi Jesper,

mg-manual is finite difference.

Thanks,

Subject: [apbs-users] APBS FD or FE

Hello,

If I run a simple mg-manual calculation, am I using finite difference (FD) or finite element (FE)?
The reason I ask is that compared to other codes I have checked I am seeing a much greater convergence behavior with APBS as a function of grid resolution and I am wondering if that is because it is using FE and the other codes are using FD. The other codes surprisingly do not really show a clear convergence behavior with grid resolution, which puzzles me a bit.

Best regards,
Jesper
