1.7 Release notes for SDT and FEMLink 6.7

1.7.1 Key features

SDT 6.7 is the only version compatible with MATLAB 8.4 (2014b) and later. Key changes of this release are

A major revision of all the SDT interfaces for compatibility with the new graphical system of MATLAB 8.4 (2014b).
Major extensions legend/filename generation capabilities, see comgui.
Significant enhancement of documentation with more readable links to be reused in sdtweb calls.
introduction of more readable Java based results tables in many functions.

Key changes for FEMLink are

ans2sdt major extension of CDB reading capabilities and bug fixes associated to changes in MATLAB R2013a behavior and 64 bit pointers in newer ANSYS versions. Reading of mapping is now supported. Reading of stresses and other ESL output in .rst files.
nasread better handling of CROD cases that correspond to bar1. Support of rectangular DMIG writing. Enhanced PBEAM,PROD translation.
abaqus more consistent reading of steps the BuildCase command allows setting-up the case relative to a desired step. Revision of the resolve command to enhance handling of node and element sets in general cases (compatibility with assembly of part instances). Translation of contact (for the *CONTACT PAIR command) to the contact module or SDT/NL, see section 1.5, is now supported for most classical rules. *Orientation properly translated into pro.MAP.
samcef improved multiple files with INPUT cards. Detailed improvement of .AEL, .FRA, .MCT, .STI, ...

For MATLAB compatibility see section 1.7.3.

1.7.2 Detail by function

comgui	major revision of image (ImWrite), filename (ImFtitle) and legend (def.Legend) generation utilities.
	Major extensions of the grouped object setting objSet commands used by SDT for figure and object formatting. Name generation extended and properly documented in objString
	Export of java tables to LaTeX/csv/text formats.
cinguj	major rewrite of the JAVA based GUI part of the toolbox with many bug fixes. A static javapath is now desired and fixed with sdtcheck('PatchJavaPath').
fe2ss	introduced -cpx command option for complex mode state-space support where hysteretic damping models can be used. This complements the alternative -loss2C. fe2ss SysDef now support restitution of enforced displacement.
feplot	significant extensions of colormaps. Full rewrite of fecom AnimMovie.
feutil	extended support for non OpenFEM face numbering schemes. OptimDegen transforms degenerate elements to their lower node number counterpart. Extended support of silent mode with ; at end of command.
feutilb	provides commands CombineModel and SubModel to support combination of models or extraction of submodels with clean handling of Stack, Mat/Pro, Case entries.
fe_case	more robust handling of hysteretic damping assembly for interpolated materials. Introduced fe_case SetCurve commands to easier handling of time/frequency varying loads.
fe_ceig	first order correction is now supported with CeigMethod=2.
fe_cyclic	support of inertial loading on partial model.
fe_eig	GenMass command generates table of generalized masses.
fe_exp	major rewrite of function and documentation to support newer data structures and optimize performance.
fe_load	improved support of DofLoad.
fe_mat	robustness of unit handling, extensions of material law interpolation.
fe_mpc	FixDofBas2mpc supports transform of local basis FixDof to MPC entries. DofSetMerge combines multiple DOFSet into one, which is the only case supported by most solvers.
fe_sens	tdofTable handling of sensor definitions as tables has been further documented and robustified.

fe_range	significantly extend commands previously in fe_def('range') for DOE handling.
fe_simul	extended support of damping and enforced input (DofSet) entries in direct frequency response.
fe_time	support for enforced displacement with DOFSet entries has been introduced.
fe_time	significant extensions and performance enhancements for explicit solvers.
fe_mknl	optimized support for node numbers above 2e9. Robustness and documentation extensions for pro.MAP.
fe_stress	computation of Von Mises stress is now compiled.
iicom	significant extension of support for 2D plots (contour, image, ...). Robustness and documentation improvements of multiple image generation ImWrite.
iimouse	major rewrite for R2014b compatibility, interactivity with java tables (comstr -17). Support of docking and datatip interactivity. Additional keyboard callbacks (press ? in iiplot or feplot).
id_rc	enhanced support of error and quality indicators of identification quality.
id_rm	robustness and GUI enhancements.
ii_mac	significant GUI rewrite in particular for table generation.
ii_mmif	robustness enhancements for signal processing capabilities.
ii_plp	major extensions of Legend, TickFcn, introduction of new ColorMap
m_piezo	support for a database of commercial piezo patches has been introduced. Materials have been added and properties corrected.
nor2ss	fixed compatibility issues with the Control Toolbox and Simulink. Improved warnings.
p_piezo	introduced new Tab commands to display model and material properties in a easily readable forms.
p_solid	improved support of anisotropic materials and composite shell.
res2ss	notable rewrite and fixed compatibility issues with the Control Toolbox and Simulink.
sdtweb	significant robustness enhancements. Improved _TagList. Introduction of _find command for file search.
setlines	improved compatibility with comgui objSet.
ufread,ufwrite	improved compatibility LMS-Testlab and performance enhancements.
cbush,celas	improved support for gyroscopic matrices and loss factor.

1.7.3 Notes by MATLAB release

MATLAB 7.6 (2008a) to 8.5 (2015a). SDT & FEMLink 6.7 are developed for these versions of MATLAB and are fully compatible with them.
MATLAB 7.9 has known compatibility problems in its HDF library and should be avoided for large FEM applications using sdthdf.
Earlier MATLAB releases are no longer supported.
