1.9 Release notes for SDT and FEMLink 6.8
1.9.1 Key features
SDT 6.8 is the only version compatible with MATLAB 8.6 (2015b) and 9.0 (2016a) mostly due to ongoing improvements of MATLAB graphics. Key changes of this release are
A continued upgrade for SDT GUI with additional interactive java tabs. Image generation, described in section 8.1, illustrates definition of projects Project for output file generation and handling of style sheets in OsDic. The java library cinguj.jar must be on the static path (check with sdtcheck('PatchJavapath')). Developer level documentation of GUI functions is now included in section 8.
- A major rewrite of numerical experiment handling capabilities in fe_range. In particular uses as scheduler of hierarchical parametric computations and post-processor for parametric results are documented.
- Continued extension of file generation with capabilities to generate multiple movies fecom AnimMovie, save the figure in multiple formats (.fig,.png, see comgui ImWrite), ...
- extensions Java based result tables with introduction of export capabilities, see comstr -17.
- continued development of the piezo manual. In particular extension of patch meshing in sdtweb('d_piezo#MeshPlate') and introduction of a shunt damping example (sdtweb('shunt'))
Key changes for FEMLink are
ans2sdt significant enhancements to CDB reading and writing with extended element and material/section property support. Performance fixes for emat reading.
- nasread fixed problems with multiple case importing, implementation of gravity translation. Automated writing of superelements as DMIG.
- abaqus significant robustness enhancements of .INP reading. Robustness of the BuildUp command.
- GUI in femlink
For MATLAB compatibility see section 1.9.3.

1.9.3 Notes by MATLAB release
MATLAB 7.14 (2012a) to 9.0 (2016a). SDT & FEMLink 6.8 are developed for these versions of MATLAB and are fully compatible with them.
- MATLAB 7.6 (2008a) to 7.13 (2011b). SDT & FEMLink 6.8 are being phased out but can be used for a number of operations.
- On Linux MATLAB 8.1 (2013a) is required.
- Earlier MATLAB releases are no longer supported.
- MATLAB 8.5 has known bugs in the handling of colorbar.
- MATLAB 7.9 has known compatibility problems in its HDF library and should be avoided for large FEM applications using sdthdf.
