Versions 1.0.*

Version 1.0.0

First issue of the library (2005/08/21). Creation of the manual.

Version 1.0.1

The new version of the library is issued 2005/08/28. A few bugs have been corrected:

• Correction for the reading of strain tensor, and curvature tensor in “op2” Nastran results file.
• Correction of small bugs in the reading of element forces.

Addition of new capabilities:

• Addition of the new functions “min”, “max” and “cmp” in the “Post” Module.
• New methods have been added to the ResKeyList class.
• The reading of strain/stress tensors, and of element forces is supported for additional element types.

The modifications of the manual correspond to the modifications of the library and of the examples:

• Modifications corresponding to the reading of strain tensor from “op2” Nastran results file. Also, a few comments about the strain tensor have been added. Correspondingly, an example has been added (section IV.2.4.4).
• Presentation of the new functions “min”, “max” and “cmp” in the “Post” module in section I.6.3.
• Modification of the presentation of post-processing data definition for the calculation of margins of safety with the Cauchy stress tensor.
• Modifications corresponding to the new methods introduced in the ResKeyList class (Chapter I.5).

Version 1.0.2

The new version of the library is issued 2005/09/11.

• The four elementary operators “+”, “-”, “*” and “/” allow now Float or Array left operands. The FeResPost library also modifies the corresponding classes.
• Correction of a few small bugs.

The modifications of the manual correspond to the modifications of the library and of the examples:

• The four elementary operators “+”, “-”, “*” and “/” allow now Float or Array left operands. The post-processing example as been modified accordingly.
• The post-processing example has been modified in such a way that the methods defined in “Post” module are included in “Main” name space.

Version 1.0.3

The new version of the library is issued 2005/11/06.

• Correction of a bug in result extraction.
• A new element coordinate system “elemIJK” is introduced.
• Several modifications have been brought to the modifications of reference coordinate systems. (Possibility of projecting coordinate systems, for example).

The modifications of the manual correspond to some of the modifications of the library, and a little more:

• Addition of Appendix X.B devoted to the thoeretical background of transformation of coordinates.
• Addition of an example illustrating the capabilities of coordinate system transformations (section IV.2.4.5).

Version 1.0.4

The new version of the library is issued 2005/11/20.

• The definition of local element (Nastran) coordinate systems has been modified.
• The “CTETRA” element is now supported.
• The reading of “op2” files is now more reliable. Previously tests were made with Nastran version 70.5 only. Now Nastran 2005 has been tested and a few bugs have been corrected.
• Also, the reading functions check the “endiannes” of “op2” files and the performs the needed corrections when reading the content. This improves the portability of the result files from one platform to another.

The modifications of the manual correspond to some of the modifications of the library, and a little more:

• Modification of the example illustrating the capabilities of coordinate system transformations (section IV.2.4.5). One more transformation is proposed. Moreover, one also gives an example with results on 3D elements.

Version 1.0.5

The new version of the library is issued 2005/12/02.

• Correction of few bugs.
• Modification of the C++ programming of op2 reading. The reliability should be improved.
• The third argument of function “modifyRefCoordSys” is now optional.
• It is now possible to manipulate CoordSys objects and store them into a DataBase.

he modifications of the manual correspond to some of the modifications of the library, and a little more: an example, presented in section IV.2.4.5 illustrates the manipulation of coordinate systems.

Version 1.0.6

The new version of the library is issued 2006/01/02.

• Correction of few bugs.
• More results types can be read from op2 files, and also results for other solution sequences can be read. (SOL 101, 103, 105 and 106 are now supported.)
• Additional Nastran cards can be read from bdf or op2 file.
• Some readings of entities in Nastran results or models can be desactivated.
• A new function allows to calculate the total force and moment corresponding to a distribution of forces and moments. (see function “calcResultingFM” in section I.4.8.
• Modification of “generateCoordResults” method in DataBase class. The method can now have three String arguments that correspond to the key to which the generated Result object is associated in the DataBase.

The modifications of the manual correspond to some of the modifications of the library, and a little more:

• Modification of the example presented in section IV.2.4.1 to illustrate the modification of function “generateCoordResults” in DataBase class.
• Addition of a new example in section IV.2.5.3 to illustrate the calculation of global force and moment transmitted by an interface.

Version 1.0.7

The new version of the library is issued 2006/02/05.

• Correction of few bugs.
• Addition of method “writeBdfLines” to the “DataBase” class.
• Addition of methods “renameResults” and “copyResults” to the “DataBase” class.

The modifications of the manual correspond to some of the modifications of the library.

Version 1.0.8

The new version of the library is issued 2006/03/26.

• Correction of few bugs.

The modifications of the manual correspond to some of the modifications of the library.
