TREECODE3D_TARG is a Fortran90 subroutine for approximating the electrostatic energy potential and force at M target particles due to the sources at N charged particles in three dimensions using an adaptive treecode.

Version 1.0 is available in a zipped tar-file here : TREECODE3D_TARG_1_0.tar.gz.

Included in the tar-file is the following README_TARG file.


TREECODE3D_TARG_OPENMP is a Fortran90 subroutine for approximating the electrostatic energy potential and force at M target particles due to the sources at N charged particles in three dimensions using an adaptive treecode. It is called from a threaded driver routine, and computes the potential and/or force on a subset of the target particles.

Included in the tar-file is the following README_TARG_OPENMP file.


TREECODE3D_YUKAWA is a Fortran90 subroutine for approximating the screened Coulomb (Yukawa) electrostatic energy potential and force of N mutually interacting charged particles in three dimensions using an adaptive treecode.

Version 1.1 is available in a zipped tar-file here : TREECODE3D_YUKAWA_1_1.tar.gz.

Included in the tar-file is the following README_YUKAWA file.
