DEVSIM TCAD Device Simulator: PDE based TCAD simulator with user-defined models
DEVSIM is semiconductor device simulation software which uses the finite volume method. It solves partial differential equations on a mesh. The Python interface allows users to specify their own equations.
It is actively being developed and more information is currently available here: http://www.devsim.org
A version of DEVSIM will be developed which is hosted through nanohub's rappture interface.
