Palace, for PArallel LArge-scale Computational Electromagnetics, is an open-source, parallel finite element code for full-wave 3D electromagnetic simulations in the frequency or time domain, using the MFEM finite element discretization library.
- Eigenmode calculations with optional material or radiative loss including lumped impedance boundaries. Automatic postprocessing of energy-participation ratios (EPRs) for circuit quantization and interface or bulk participation ratios for predicting dielectric loss.
- Frequency domain driven simulations with surface current excitation and lumped or numeric wave port boundaries. Wideband frequency response calculation using uniform frequency space sampling or an adaptive fast frequency sweep algorithm.
- Explicit or fully-implicit time domain solver for transient electromagnetic analysis.
- Lumped capacitance and inductance matrix extraction via electrostatic and magnetostatic problem formulations.
- Support for a wide range of mesh file formats for structured and unstructured meshes, with built-in uniform or region-based parallel mesh refinement.
- Arbitrary high-order finite element spaces and curvilinear mesh support thanks to the MFEM library.
- Scalable algorithms for the solution of linear systems of equations, including geometric multigrid (GMG), parallel sparse direct solvers, and algebraic multigrid (AMG) preconditioners, for fast performance on platforms ranging from laptops to HPC systems.
Palace can be installed using the Spack HPC package manager, with the
command spack install palace. Run spack info palace to get more information about the
available configuration options and dependencies.
Instructions for obtaining Palace and building from source can be found in the
documentation. Git submodules are used
to manage the builds of most dependencies, so the repository should be cloned using the
--recurse-submodules flag, or alternatively git submodule update --init can be run in
order to download the dependency source code for an existing clone.
System requirements:
- CMake version 3.13 or later
- C++17 compatible C++ compiler
- C and (optionally) Fortran compilers for dependency builds
- MPI distribution
- BLAS, LAPACK libraries

The documentation for Palace provides full instructions for building the solver and running electromagnetic simulations.
To build a local version of the documentation, run julia make.jl from within the
docs/ directory.
Some example applications including configuration files and meshes can be found in the
examples/ directory. Complete tutorials for each example are available in
the documentation.
