pytential helps you accurately evaluate layer potentials (and, sooner or later, volume potentials). It also knows how to set up meshes and solve integral equations.

It relies on

• numpy for arrays
• boxtree for FMM tree building
• sumpy for expansions and analytical routines
• modepy for modes and nodes on simplices
• meshmode for modes and nodes on simplices
• loopy for fast array operations
• pytest for automated testing

and, indirectly,

• PyOpenCL as computational infrastructure

PyOpenCL is likely the only package you'll have to install by hand, all the others will be installed automatically.
