OFELI's News

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.

February 1, 2007 - Release OFELI 1.4.6

Fixed: A bug in NodeVect class. Default field name was not defined
Class Mesh: Member functions setNodesForDOF, setElementsForDOF, setSidesForDOF, setEdgesForDOF are grouped in the new member function setDOFSupport.
Class Triang3: Member function getCircumcenter is added
Class Triang3: Member function isStrictlyIn is added

December 20, 2006 - Release OFELI 1.4.5

Added: in cmesh, conversion from Triangle mesh generator to MDF file format
Added: Handling of periodic boundary conditions for some equations
Class Laplace is moved to a subdirectory (of include and src) called Laplace and is renamed Laplace2DFET3
Added: classes for 1-D elliptic problems (in Laplace)
Fixed: A bug in output format of mesh file converters

November 6, 2006 - Release OFELI 1.4.4

November 05, 2006 - Release OFELI 1.4.3

Some source codes for demos were not present in the installed library: Fixed.
A new class 'Grid' that handles structured grids is added. A constructor in class 'Mesh' enables converting a Grid instance into a Mesh instance.
A new class 'Point2D' that is a clone of 'Point' but specialized to 2-D.

September 25, 2006 - Release OFELI 1.4.2

A bug in the ofeli-config script is fixed.
Minor bugs in installation and configuration scripts were fixed.
'include' directory has now problem oriented subdirectories.
A new mesh utility function has been added (MeshToMesh).
A new class for preconditioning (Prec) is added: it enables providing the preconditioner type as an argument in the class constructor.
