1.8 Release notes for SDT 6.5 and FEMLink 3.8

1.8.1 Key features

SDT 6.5 is the first version compatible with MATLAB 8.0 (2012b). Key features of this release are

Major update of iiplot,iicom to support more general plots (contour, surface, ...) and documented control procedures for automated inits, legend, marker lines, text based tick, ...
Major revision of feplot. Rewrite of the color field handling : support for colored vector field display, reuse of pre-computed energy at elements data structures, ... Introduction of a complete iicom ImWrite command for generation of image sequences to be included in automated reports.
Significant improvement of utilities for piezo modeling : visualization of charges and electrical fields, ...
Improved compatibility with MATLAB figure toolbar callbacks and japanese version of MATLAB.

Key features of FEMLink 3.8 are

abaqus improved reading of .fil (velocity, acceleration and resultant fields), read/write .inp (*nset, *spring, *orientation, composite and orthotropic materials, element conversion table, contact)
ans2sdt improved reading of beam sections, velocity and resultant fields in .rst files.
nasread corrected support of MAT9 and MATT entries to reflect improved implementation in SDT. Bugs were corrected with writing of rigid case entries.
samcef improved u18 reading speed and support for 64 bit format files.

For MATLAB compatibility see section 1.8.3.

1.8.2 Detail by function

The following functions have been modified.

beam1	robustness enhancements for compatibility with fe_caseg StressCut.
elem0	enhanced VectFromDir (see section 7.13)
comgui	Major rewrite of comgui ImWrite and iicom ImWrite for automated figure generation.
fe_cyclic	Build-ByMat allows interfaces with coincident nodes.
fe_case	improved handling of parameters, see upcom Par and fe_defRange
fe_caseg	Robustness enhancements in Assemble (see section 4.8.8), major extension of StressCut, ZoomClip.
fe_curve	corrected errors on noise generation for odd numbers of samples.
fe_gmsh	significant extension of CAD definition commands.
fe_def	fe_defRange commands for the description of design maps are now documented. Many detail robustness enhancements.
fe_mat	robustness enhancements for unit conversion (convert command) and for support of interpolated properties, see section 7.3.
fe_mpc	model=fe_mpc('Rbe3Id',model) generated unique identifiers for RBE3 constraints.
	Handling of local displacement coordinates was corrected and documented.
fe_quality	improved integration in feplot and robustness.
fe_reduc	Free (reduction on free modes) now supports DofSet (enforced displacement) commands. A .UseLoad option has been added to CraigBampton to allow computation of load residuals for a Craig Bampton reduction.
fe_sens	rewriting of the gartte and gartsens demos associated with robustness enhancements.
fe_stress	output of the Enerprovides newer options and output in the newer curve format. feplot now allows dynamic switching between energy value, density or group value.
fe_time	improved implementation of Theta method integration.
feplot	complete rewrite of ColorData for energy computations, ColorScale for more accurate display, field display for StressCut.
	improved support of HDF file delayed reading.
feutil	Major extension of the feutil SetPro command. Improved handling of surface sets. GetDof corrections for master DOFs in rigid elements.
feutilb	Match implements a new node matching strategy as MatchSurf and has undergone significant speed enhancements. CombineModel supports extended renumbering.
idcom	improved integration of Error computations. GUI robustness improvements.
ii_plp	significant rewrite and documentation of iiplot PlotInfo utilities. Significant extensions of the Legend command. Documentation of the TickFcn capabilities.
iiplot	documentation was revised to include PlotInfo in particular.
	compatibility with MATLAB figure toolbar callbacks (including datatip) was improved
	Mouse editing of xlabel, ... is made persistent when scanning through channels by modification of the comgui objSet commands applied to ua.axProp.
iicom	rewriting of the SubSave command to allowing easier switch between multiple views.
	Show now supports 3D (f(x,y)) plots more consistently : inits, cursor, surface, contour, ...
	CurveInit clarifies the init and display. PoleLine, ImWrite are revised and better documented.
q4cs	improved integration of stress computations.
p_piezo	charge and electrical field viewing are available.
p_solid	material coordinate systems are now supported for anisotropic elasticity. Improved Default command and support of constitutive law output.
sdtweb	major rewrite for links at support of _tagList command that opens the MATLAB editor at proper lines.
setlines	objSet has been documented.

1.8.3 Notes by MATLAB release

MATLAB 7.6 to 8.0 (2012b). SDT 6.5 and FEMLink 3.8 are developed for these versions of MATLAB and are fully compatible with them.
MATLAB 7.5 is fully compatible with the exception of the new curvemodel object which requires the newer MATLAB object.
Earlier MATLAB releases are no longer supported.
