SDT 6.6 is the first version compatible with MATLAB 8.2 (2013b) and 8.3 (2014a). Key changes of this release are
Key changes for FEMLink are
For MATLAB compatibility see section 1.8.3.
Outside documentation and demos in sdtdemos, the following functions have been modified.
| comgui | enhancement of automated image generation with ImWrite. |
| fe2ss | systematic treatment of fe_load DofSet was introduced and tested for piezo application. In compatibilities with control toolbox were corrected. |
| fecom | improved generality and documentation of color scaling options. Energy sums by group in InfoMass are more general. |
| fe_case | SensDof sensor and stress-cut handling was robustified and further documented. Labels for unique DOFs are more consistently filled. |
| ConnectionSurface supports a new MatchS option that can be very much faster. | |
| fe_curve | enhancements and revision of documentation of test curves and commands for fe_load. |
| fe_cyclic | now supports periodicity condition building based in DOF rather than nodes. This is important for multi-physic applications. |
| fe_def | robustness of AppendDef and SubRef was enhanced. Range commands for the representation of experiments (parameters of a design space) were extended. |
| fe_gmsh | interface and documentation enhancement. Partial read of geometry files. |
| fe_mat | unit conversion was enhanced with new call formats and now support piezo-electric properties. |
| fe_mknl | introduced an optimized strategy for matrix preallocation. |
| fe_norm | memory footprint was improved for intensive operations. |
| fe_quality | interaction with feplot for viewing mesh quality was improved. |
| fe_reduc | a new Call command now supports user defined methods, while keeping the standard model initialization. Free-bset is a new option for enforced motion. |
| fe_simul | improved handling hysteretic damping and enforced motion for full order frequency computations DRFR. |
| fe_stress | GetTop supports handling of stress topologies coming from external FEM codes. |
| fe_time | .Follow handling and theta method implementation were revised. |
| fesuper | the new command DefCh supports expansion for specific DOF. This is used for on the fly display of responses in superelements. SeInfoNode recurses in components for information about elements connected to a node. |
| feutil | support with silent operation using the ; command option was extended. |
| idcom | implemented silent versions of most commands (ending by ;). The error indicator now also provides a contribution indication that quantifies the modal contribution with respect to overall transfer level. |
| a contribution indicator was added to the error plot. | |
| ii_mac | default table output is now in java |
| matgui | matgui('jpl',model) supports java rendering of properties. |
| nor2ss | LabOut and LabIn commands are used for robust interaction with toolboxes from the MathWorks. |
| p_beam | clarified documentation and robustness of subtype 3 (standard sections) |
| q4cs | now supports piezoelectric shell formulations for topologies other than the quadrangle. |
| sdt_locale | new function supporting handling of button definitions in CSV files. Supports the generation of extensible GUI. |
| mklserv_utils | an external ofact solver based on MKL Pardiso. This solver is much faster at factorization than the base spfmex. This patch to SDT can be downloaded with sdtcheck patchMkl. |
| mkl_utils | supports optimized residual computations in fe_time. This patch to SDT can be downloaded with sdtcheck patchMkl. |
| m_elastic | -therm used to include thermal constants in database material properties. Improved support for composite materials. |
| p_beam | improved documentation of predefined sections. |
| p_shell | improved support for composites. |
| sdtweb | development of navigation with _tagList was continued, documentation was improved. |
