# What is new from version 7.2 to beta version 7.4b

#

NEW FEATURES - PREPROCESS New mesh renumber option. Setting the variable 'RenumberMethod' to 1, after generate a mesh, the nodes are renumbered with a Reverse Cuthill-McKee algorithm. (setting 0 the old renumber method is applied, and setting -1 the mesh is not renumbered). For future versions new algoritms can be included. Add to dev_kit.tcl some procedures to select GiD coordinates or entities: ::GidUtils::GetCoordinates, ::GidUtils::PickEntities (useful for tcl-problemtype developers) Translation: Added to general prefences a language option. It's possible to add a new language copying inside scripts\msgs the apropiate language catalog message file (es.msg, de.msg, etc.) Custom Render: The user can define new render styles, selecting the layer color to draw entities, the visibility, width, etc. (menu View->Render->Customize...) Acis Import: updated to ACIS 7 format. Parasolid Import: updated to Parasolid 11 format. New Shapefile import (useful GIS format). Tcl/Tk: internal GiD interpreter updated to Tcl/Tk 8.4.1 version. Encryption functions. Backup: each GiD store your own backup, and ask the user to restore the model if GiD crash. Bas template: new commands *ElemsType, *ElemsTypeName, *SetFormatForceWidth, *SetFormatStandard, *nelem(OnlyPoints, *set elems(OnlyPoints). Tcl: it's possible cancel the calculation from the tcl-GiD event procedures 'BeforeWriteCalcFileGIDProject' or 'BeforeWriteCalcFileGIDProject' returns '-cancel-' (to check data input before calculate). Tcl: new tcl-GiD event procedures BeforeGenerateMesh and AfterGenerateMesh. Play sound general preference: to play a sound when some task is finished. General preference 'Shrink windows when selection' to resize some windows (layers, conditions...) when selecting to facilitate this selection. Procserver: get remote calculation server info (available groups,...). It's possible to set the number of a new volume or planar surface (useful for scripts automatization). Variable 'CalcWithoutMesh' to write the calculation file without mesh entities (for some special problemtypes). New specialized GiD-tcl commands to manage conditions, materials, local axes, mesh edit , etc (GiD_ModifyData, GiD_AssignData, GiD_CreateData, GiD_LocalAxes, GiD_IntervalData, GiD_Mesh ). New GiD-tcl command drawopengl to directly draw in GiD from tcl scripts. Import/export materials updated for book and special fields support, and accepted blank lines in material or condition file. Iges export: if the problemtype has model units, then write this units in the iges output file. GiD-tcl info command: new order info parametric line|surface to obtain coordinates, derivatives, etc. Nastran import: new GiD-tcl event procedures to process information in the problemtype. DXF export: try to export surfaces as 3Dface if possible or else an approximate polyface mesh. RecentFiles menu to access to the last models. Fast surface render for some simple cases. Edge collapse enhanced. New utilitis to mesh edit (smooth a selection and map nodes over geometry). Mesh from boundary command to generate tetrahedras from a triangle boundary. Move node utility enhanced, deleting collapsed nodes and elements.

NEW FEATURES - POSTPROCESS New right buttons look View can be accesed directly through TclTk with '.central.s info view' and '.central.s process view set view ""' New 'Utilities->graphical->animation script' window which allows the user to define a sequence of scenes which will be animated New 'Utilities->Report' window for creating reports: images, List Entities info, text, etc. can be inserted. Changed the boundaries calculation algorithm, should be faster and uses a little less memory than before, also for preprocess- Smooth Contour fill: shows a contour fill with smoothed gauss points results: min, max and mean value of the nodal extrapolated results Labels, dimensions, comments, legends and axes are scaled with High resolution printings ( >200dpi). Cuts can be done giving the coeficients of the cut plane: Ax + By + Cz + D = 0 The lines of the volume meshes are also drawn when the option 'draw interior' is on, and not only the internal faces as before Background image and texture also in JPEG format

CORRECTED BUGS - PREPROCESS Errors with temporary files with not occidental operating systems (japanese, Corean, etc) using filenames with not ASCII characters. Check of bas numeric format before apply, to avoid crash using some incorrect format. The user can cancel the 'quit' function if some process is still running. Corrected mesh quality graph bugs with small elements. Corrected internet retrieve bug with some fast connections. Bas template: *break can exit a for or a loop IGES export: bad output file extension if the user not assign any extension. IGES import: more tolerant to files with incoherent data (bad parameter count field 14, etc.) Corrected read/write bug of GiD Ascii files with conditions over layer. Corrected crash creating a surfmesh from a quadrilateral mesh. A condition over face elems is applied in a interface between materials to two elements instead to select only one. Corrected bug of aditional random blank spaces in the calculation file. Corrected slow Reverse Cuthill-McKee renumbering with 1-noded elements. Swapped bad orientation of volume elements created with a copy/move by mirror. Corrected a bug calculating the area of some trimmed surfaces. Avoided geometric entities renumber when generate a mesh. Corrected a bug generating tetrahedras with background mesh sizes.

CORRECTED BUGS - POSTPROCESS Corrected bad precision calculating eigenvalues and eigenvectors for tensor results. Corrected the gausspoints extrapolation with given natural coordinates and for cuadratic elements Corrected bug when changing number of colors and contour fill and visualizing several results at once Corrected some problems while animating several results at once Correction while reading tecplot files with hexaedras Some corrections for the legend and the c.fill ranges for extreme situations: range width too small, limits too close, < epsilon When changing the render style for the meshes, it changes the render of the isosurfaces too Correction when projecting a texture to the border of the mesh Correction when cutting more than 100 meshes and when cutting volume meshes Some corrections when selecting results, analysis and steps with the same prefix Corrected the merge(Ascii) option which didn't merge partial values of the same result/step/analysis Independent behaviour for the 'animation controls' and 'animation results' windows Correction of the 'Read Batch' windows which swallows the quotes of the batch file
