All PHAML (Parallel Hierarchical Adaptive MultiLevel) is a Fortran module for the solution of elliptic partial differential equations. It uses finite elements, adaptive grid refinement (h, p or hp) and multigrid solution techniques in a message passing parallel program. It has interactive graphics via OpenGL. This document is the user’s guide for PHAML. The first part tells how to obtain any needed software, how to build and test the PHAML library, and how to compile and run the example programs. The second part explains the use of PHAML, including program structure and the various options that are available. The third part is a reference manual which describes the API (application programming interface) of PHAML. The reference manual begins with a 2 page Quick Start section for the impatient. Keywords: adaptive grid refinement, dynamic load balancing, elliptic eigenvalue
