## Software Features:

* Python scripting 
* DC, small-signal AC, impedance field method, transient
* User specified partial differential equations (PDE).
* Extended floating point precision
* 1D, 2D, and 3D simulation
* 1D, 2D mesher
* Import 3D meshes.
* 2D cylindrical coordinate simulation
* ASCII file format with PDE embedded.
