OFELI's News

March 1, 2010 - Release OFELI 2.0.2

Added: Class interface classes for Level Sets ande Fast Marching
Added: Figure classes for defining geometric figures and computing signed distances

January 2, 2010 - Release OFELI 2.0.1

Added: Class Funct for function Parsing
Added: Class Tabulation for function tabulation and new tags in XML files for tabulated functions

September 10, 2009 - Release OFELI 2.0.0

New version with fundamental changes:

OFELI has now changed to LGPL license: It can now be used in proprietary codes and libraries
A bug in cfield: Conversions of fields now work
Calculation of gradient, curl and divergence in vector classes
A bug in DSMatrix is fixed
A new class (Eigen) for computing eigenvalues and eigenvectors is added
A new demo code for computing eigenvalues and eigenvectors is added
And many other modifications ...

March 22, 2009 - Release OFELI 1.7.0

This is a major release containing number of changes.

Complete portability to gcc 4.3 is now guaranteed
Old format files are now deprecated and no more documented. Only XML files are to be used
A bug in cmesh: Conversion from gmsh file format is fixed (node codes were not correctly transmitted) (Thanks to S. Clain).
A bug in class DC3DT4 is fixed (Thanks to O. Corral).
A bug in Mesh constructor using Grid instance is fixed.
Class VDF is removed from the library.
Consistent capacity contribution in class DC3DT4 is implemented (contributor: Octavio Corral).
A bug in cfield: The case of vector fields os now fixed
Added: Macros for loops on elements, nodes or sides ... See tutorial lessons for instance.
Be careful: Some of these macros use new global variales (theNode, theCNode, theElement, theCElement, theSide, theCSide) which are pointers to Node, Element, Side in nonconstant and constant versions respectively
Added: class Laplace2DFVT for the Laplace equation in 2-D using triangular finite volumes

October 20, 2008 - Release OFELI 1.6.0

This is a major release containing number of changes.

The directory tests previously containing simple examples and demo programs is now split into 2 directories:
- A directory tutorial contains the old examples, called now lessons
- A directory demos contains the old demos subdirectory
The directory Win32 is replaced by a directory called tools with two subdirectories:
- The subdirectory Win32 remains the same
- The subdirectory Codeblocks provides material for developing projects in CodeBlocks. This one is is a multiplatform application and is available at http://www.codeblocks.org
All predefined file formats for input and output are replaced by an XML file format. Old file format will be kept for some time and then abandoned
Old MDF and FDF files can be converted into XML file by using the added utility programs mdf2xml and fdf2xml respectively
Class VDF is now called Prescription. This one deals however with XML files only
A new class IOField replaces old FDF class and enables handling new XML field files
Functions to store and read mesh and field files in XML file formats are called getMesh, saveMesh and saveField

December 20, 2007 - Release OFELI 1.5.2

Fixed: A bug in ofeli installation: doc file demos.pdf was replaced by Demos.pdf
Fixed: A bug in member function Tetra4::getRefCoord
Fixed: A bug in building dev-cpp projects
More newer classes are now documented

August 25, 2007 - Release OFELI 1.5.1

Added: in Documentation, PDF files containing presentations and examples of the library
Modified: In class Mesh: Node, Element, Side and Edge lists are now instances of valarray rather than vector : Faster. Sorting is implemented in OFELI by qksort.
Added: In file MeshExtract.h: New classes to construct lists of nodes, elements or sides with specific properties (e.g. common code)
Fixed: A bug in class Mesh: Some useless member functions were declared but not implemented
Fixed: A bug in class Point (== and != operators)
Added: A constructor in class Mesh to extract the mesh of a rectangular subdomain

June 1, 2007 - Release OFELI 1.5.0

A bug in member function FDF::Get(NodeVect &) was fixed.
A bug in member function FDF::Get(Vect &,...) was fixed.
Added: Loop on boundary sides in Mesh: Now use topBoundarySide and getBoundarySide : Faster
Added: Loop on markes boundary nodes in Mesh: Now use topMarkedNode and getMarkedNode : Faster
Added: Utility functions 'print' for matrix classes to print part of matrix
Added: Utility functions 'print' for Vect class to print part of vector
Added: TCLAP library for argument parsing
Added: setPrintView methods
Added: A new class Laplace2DMHRT0 to solve the Laplace equation by the Mixed Hybrid RT0 method.
Added: Operators +=, -=, *= and /= for constants in class Vect<>
No control of element jacobian and number of nodes is now checked in shape function classes => More efficiency.
Conversion utility functions cmesh and cfield have now a different list of arguments. Please refer to documentation.
