Revision Log

FlexPDE is an evolving product. It is also a complex product. The addition of new features and the repair of errors occasion the release of new versions at frequent intervals. In this section we present a brief history of the changes made in FlexPDE. The most recent version is listed first, followed by increasingly older versions. FlexPDE version numbers encode the exact release.

Version 8.00    12/01/23

FlexPDE Version 8 is a major rewrite of the FlexPDE application.

Among the new features in the initial release of FlexPDE version 8 are:

  • Enhanced Internet Licensing Options - Auto-release option, multi-seat option, online access/management to license state.
  • OpenGL plots - New selectors for mesh, contour, and surface plots using OpenGL.
  • Moving Mesh Reconnect - Automatic mesh reconnection for moving meshes maintains uniform cells.
  • Rotational Extrusion - Extrude in radial angle instead of in Z. Makes conversion of 2D cylindrical models to 3D a snap!
  • Complex Eigenvalues - Solve models that produce complex eigenvalue solutions.
  • Explicit Variables - Set any variable to an explicit expression in specific regions.
  • SVG Graphics Export - Export any plot in Scalable Vector Graphics format.
  • Generalized Periodicity - Periodic Map now allows variable exchange. Great for exchanging vector components.
  • More Hyperbolic Functions - Addition of COTH, SECH, and CSCH hyperbolic functions.
  • New Distance Function - Edge distance function to calculate the distance along a named path.
  • New Utility Functions - New pseudo FLOOR and CEILING functions as alternatives to Max and Min, that provide a continuous derivative.
  • Many Internal Improvements - Improved TRANSFER file format, improved error measure, improved parameter/equation summaries in debug file, and improved diagnostics for discontinuous Jacobians interfering with Newton convergence.
