Version 3.03f    4/15/03

Modifications:

• Adds selector NOFEATUREPLOT to supress gray traces of features in contour plots.

Corrections:

• Corrects an error in importing multiregion TransferMesh files.
• Corrects an error in connecting mixed lines and polylines in DXF import files.
• Corrects a double incrementation of file name sequence suffixes in staged or time dependent Transfer exports.
• Corrects strange behavior of timestep control in problems with abruptly switched boundary conditions or sources.

 Version 3.03e    1/30/03

Corrections:

• Corrects an error in network license handling on Windows platform..

Version 3.03d    1/20/03

Modifications:

• Increases the node limit for 3D problems in the Student Version to 1600.
• Allows second derivatives in boundary conditions in 3D.

Corrections:

• Correctly differentiates the SUM function.
• Corrects an error in problems with more than 32767 value boundary condition nodes.
• Corrects an instability due to bad scaling of solution increments when the Conjugate Gradient iteration fails.
• Corrects an error in coupling Scalar Variables to boundary conditions.

 Version 3.03c    11/26/02

New Features:

• Command-line switch -m runs in minimized mode, -q combines -r -x -m.  Use -q when running FlexPDE from controllers or batch files.  [Note: -m is not implemented under Mac OS X].

Modifications:

• Sends an error diagnostic for NORMAL and TANGENTIAL functions when passed a string argument.

Corrections:

• Corrects a timing error with -x switch under Linux.
• Corrects double-strike requirement for "View" mide hotkeys. [Note: "View" mode hotkeys do not work under Unix/Linux - we are investigating].
• Corrects export file variable labelling and other errors related to end-of-line imbedded in argument lists..
• [3.03b1]
• Corrects a memory protection fault under Linux.
• Corrects a DLL link problem under Windows 98.

Version 3.03b    11/11/02

New Features:

• Supports Mac OS X version 10.2 (Jaguar).

Corrections:

• Corrects timing of MOVIE view under Linux.
• Corrects memory protection fault when rotating a maximized surface plot.
• Corrects clip window in EPS graphic exports.
• [3.03b1]
• Corrects a memory protection fault under Linux.
• Corrects a DLL link problem under Windows 98.

Version 3.03a    9/28/02

New Features:

• Adds support for single-user USB license dongles on Windows platform.

Version 3.03    9/16/02

New Features:

• New vector mode graphic export formats: Encapsulated PostScript and Windows Enhanced Metafile format (EMF).  EMF is available only on Windows versions.
• A search function has been implemented in the editor.  Search begins at the cursor position, and may be repeated to find the next instance of the search pattern.
• The editor now saves the font selection for use in subsequent invocations of FlexPDE.

Modifications:

• Modified tuning for linear steady-state solutions improves performance.  (To remove this modification and recover previous behavior, use SELECT DEGRADECG=OFF.)
• Omits the "Quit FlexPDE?" query on exit.  If files have been modified, you will be asked whether they should be saved.  If a problem is running, you will be asked whether to kill the job.

Corrections:

• Corrects the "undo" function in the editor.
• Corrects a few occasions for memory protection faults.

New Examples:

• "Samples | Steady_State | Fluids | 3d_Flowbox.pde"      shows a 3D implementation of Navier-Stokes equations.
