In a nutshell, semba-fdtd capabilities are
-
Cluster working capabilites through MPI.
-
Multiple threads per processor through OpenMP.
-
Closed/symmetric problems by means of PEC and PMC conditions.
-
Open problems by means of PML boundary conditions (CPML formulation) or by Mur ABCs.
-
Non-uniformly meshed domains by means of mesh-grading techniques.
-
Bulk lossless and lossy dielectrics.
-
Materials with frequency dependent relative permittivity and/or permeability, with an arbitrary number of complex-conjugate pole-residue pairs.
-
Bulk anisotropic lossless and lossy dielectrics.
-
Equivalent models of multilayered skin-depth materials.
-
Branched multiwires:
-
Junctions of wires of different radii.
- Junctions of multiwires.
- Wire bundles.
- Loaded with p.u.l resistance and inductance wires.
- Grounding through lumped elements.
-
Plane-wave illumination with arbitrary time variation.
-
Multiple planewaves illumination for reverberation chamber modeling.
-
Hertzian dipole sources.
-
Equivalent Huygens surfaces.
-
Low frequency thin composites and lossy surfaces.
-
Thin slots.

Near-to-far field transformation.
It is important to point out the repository has dependencies which are available as submodules. It is necessary to run git submodule init
and git submodule update
from the root folder before running any cmake
or build
commands.
Install intel runtime libraries: https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html
Tests must be run from the root folder. python
wrapper test assumes that semba-fdtd
has been compiled successfully and is located in folder build/bin/
. For intel compilation it also assumes that the intel runtime libraries are accessible.
semba-fdtd
uses the following format as input files.
