The installation files presented on this page will install FlexPDE 8 in Lite mode and can be used free for evaluation. In this mode, unkeyed scripts that you create will be restricted to five simultaneous equations, as well as 100, 400, and 1200 mesh cells in 1D, 2D, and 3D, respectively, for a cubic model. (The cell maximum is based on the interpolation order and will increase for quadratic and linear models.) You can also run problems which have been specially keyed by PDE Solutions Inc. (see the Sample Applications). All keyed problems will run in full Professional mode. You can change any numeric or textual (string) item in a keyed demo problem without invalidating the key!
The Lite version can be unlocked to Professional mode by installing a license key of the appropriate 1D, 2D, or 3D configuration. See Licensing to request a 30-day free trial or Pricing to see the pricing structure or Buy Academic or Buy Commercial to purchase a license.
Licensed version 8 users can install over an older version in the 8.x series; your license key remains valid. Users of FlexPDE version 7 or earlier can install version 8 without invalidating your existing application. Version 8 installs in a separate folder, and uses a different license key or dongle.
