openEMS Features:

• fully 3D Cartesian and cylindrical coordinates graded mesh.
• Multi-threading, SIMD (SSE) and MPI support for high speed FDTD.
• Octave and Matlab-Interface
• Dispersive material (Drude/Lorentz/Debye type)
• Field dumps in time and frequency domain as vtk or hdf5 file format
• Flexible post-processing routines in Octave/Matlab
• and many more

Install Instruction

Requirements

Ubuntu

• Install all necessary dependencies, e.g. on Ubuntu 18.04 and above:
  

sudo apt-get install build-essential cmake git libhdf5-dev libvtk7-dev libboost-all-dev libcgal-dev libtinyxml-dev qtbase5-dev libvtk7-qt-dev

Note: For later versions of Ubuntu you may have to choose a later version of vtk.

• Optional: Install octave and octave devel packages:
  

sudo apt-get install octave liboctave-dev

• Optional: For the package hyp2mat you need additonal dependencies:
  

sudo apt-get install gengetopt help2man groff pod2pdf bison flex libhpdf-dev libtool

• Optional: For MPI support:
  

sudo apt-get install libopenmpi-dev

Clone, build and install

• Clone this repository, build openEMS and install e.g. to "~/opt/openEMS":
  

git clone --recursive https://github.com/thliebig/openEMS-Project.git
cd openEMS-Project
./update_openEMS.sh ~/opt/openEMS

or including hyp2mat and CTB and MPI:

./update_openEMS.sh ~/opt/openEMS --with-hyp2mat --with-CTB --with-MPI

• Add the given paths to your Octave/Matlab environment (e.g.):
  

addpath('~/opt/openEMS/share/openEMS/matlab');
addpath('~/opt/openEMS/share/CSXCAD/matlab');

• Add the optional packages to your Octave/Matlab environment (e.g.):
  

addpath('~/opt/openEMS/share/hyp2mat/matlab');
addpath('~/opt/openEMS/share/CTB/matlab');
