A FDTD solver for electromagnetic wave simulations on a GPU cluster
KEMP is a fast FDTD solver on a GPU-based cluster. The FDTD (Finite-Difference Time-Domain) method is a popular numerical method for electromagnetic field simulations. KEMP enables hardware accelerations suitable for multi-GPU, multi-core CPU and GPU cluster. KEMP also provide easy configuration by using Python scripting language.
GENESIS (GEneral NEural SImulation System) is a software platform for the simulation of neural systems ranging from subcellular components and biochemical reactions to complex models of single neurons, large networks, and systems-level processes.
VOpR - A Virtual Optical Rail
VOpR allows to create and evaluate simple optical systems, in which the basic optical elements are arranged along the optical axis. The current supported optical elements are:
spaces,spherical lenses, circular apertures and flat blocks of some optical medium.
The program has three main components:
1. The database editor. Currently the database can store data about:
-optical materials,
-spherical lenses,
-projection properties of light sensors and...
CAMFR (CAvity Modelling FRamework) is a fast, flexible, friendly full-vectorial Maxwell solver. Although it can tackle general electromagnetic problems, its main focus is on applications in the field of photonics.
