1.8  Release notes for SDT and FEMLink 6.8

1.8.1  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

Key changes for FEMLink are

For MATLAB compatibility see section 1.8.3.

1.8.2  Detail by function

beam1supports the Beam1In flag to avoid use of inertia correction.
cbushfixed problems with use of node in element for local orientation definition and hysteretic damping computations.
comguimajor extensions of the image writing capabilities. Export to Word and PowerPoint is now included with the project definition. Movie generation with the .gif extension and multi-extension (for example .png and .fig) are now included. Improved cropping options. Improved file name generation and interaction with projects, see comgui PlotWd. Introduction of style sheets, see OsDic.
fe_coorrobustness enhancements for enforced motion problems opt(1)=4.
