Download

You can download and save to a temporary directory

• SDT 6.0 standard version 30MB (SDT and FEMLink with source code)
• SDT 6.0 demo version 33 MB (SDT and FEMLink without restriction but no source code).
  

For compatibility with MATLAB version see the compatibility chart.

Generate a licence request

• To generate a license request. Within MATLAB, change your current directory to wherever you downloaded the distribution, and run the distribution file

   >> cd /tmp % or wherever you downloaded sdt60_dis or sdt60d_dis
   >> sdt60_dis
  

  This will open the license request building GUI shown below. Fill in the appropriate values and mail the result to license@sdtools.com so that a license key can be generated for you. To generate a license key, we require your professional coordinates and that of your reseller if any.
  
  
  
  

Install the distribution

• If you want to preserve a previous copy of the SDT rename the $matlabroot/toolbox/sdt directory.
  
• Start MATLAB, as a user who has write permission on the matlabroot directory (Administrator for Windows, root for UNIX systems).
  
• Within MATLAB, change your current directory to wherever you downloaded the distribution, and run the distribution file

   >> cd /tmp % or wherever you downloaded sdt60_dis or sdt60d_dis
   >> % target='my_dir_location' % you may define the target here
   >>  SDT_license_key='10-00000-00000-00000-00000-00000'
   >> sdt60_dis
  

• Select what you want to install, check that the target directories are correct.
  
  
  
  
  
• When ready press the Install button. Install extracts the proper files, checks the configuration of your installation of the SDT and edits toolbox/local/pathdef.m file so that the SDT becomes included in the your default matlabpath.

Re-install the distribution

• If you want to preserve a previous copy of the SDT rename the $matlabroot/toolbox/sdt directory or define at different target below
  
• Start MATLAB, as a user who has write permission on the matlabroot directory (Administrator for Windows, root for UNIX systems).
  
• Within MATLAB, change your current directory to wherever you downloaded the distribution, and run the distribution file

   >> cd /tmp % or wherever you downloaded sdt60_dis or sdt60d_dis
   >> target='my_dir_location' % you may define the target here
   >>  SDT_license_key=sdtdef('key'); % use your previous key
   >> sdt60_dis
  

• Select what you want to install, check that the target directories are correct.
  
  
  
  
  
• When ready press the Install button. Install extracts the proper files, checks the configuration of your installation of the SDT and edits toolbox/local/pathdef.m file so that the SDT becomes included in the your default matlabpath.

Multiple SDT or MATLAB installations

• If you have multiple installations (various versions of SDT or a single SDT for multiple MATLAB), you should use a dynamic path generation rather than the default editing of pathdef.m. This is in particular necessary with multiple MATLAB versions since the path order changes. In your startup.m (see doc startup in MATLAB) simply place the lines

   pw0=pwd; cd('my_sdt_location'); % the SDT you want to use
   % cd(fullfile(matlabroot,'toolbox','sdt')) % is default
   sdtcheck('path'); 
   cd(pw0); clear pw0
  

• To create multiple SDT installations, install using

   >> cd /tmp % or wherever you downloaded sdt*_dis
   >> target='my_dir_location' % define the new target
   >> target=fullfile(matlabroot,'toolbox','my_other_sdt');
   >> SDT_license_key=sdtdef('key'); % use your previous key
   >> sdtcheck('pathnode'); % clean paths of unused SDT
   >> sdt60_dis
   >> rehash toolboxreset % force clean the toolbox cache
  

  and use the step above to switch between installations

Problems installing on a server

If you do not have write permission for the server where the target MATLAB is installed. Install the toolbox to directories in your account (select different directories for SDT, SDT_HELP and SDT_PDF. When done installing, ask your administator

• install the toolbox in your account (in Matlab run the following commands)

   cd /tmp % or wherever you downloaded sdt60_dis or sdt60d_dis
   target='~/sdt' % 
   SDT_license_key='10-00000-00000-00000-00000-00000'
   sdt60_dis
  

• to copy the directories to the server

   # edit these lines to appropriate values ####
   setenv MATLABROOT /usr/local/matlab 
   setenv SDT ~/sdt
  
   cp -R $SDT $MATLABROOT/toolbox/sdt
   chmod -R a+rX $MATLABROOT/toolbox/sdt
   chmod -R a+x  $MATLABROOT/toolbox/sdt/*.mex*
  

• edit the default matlab path fullfile(matlabroot,'toolbox','local','pathdef.m') to include

   matlabroot,'\toolbox\sdt;',...
   matlabroot,'\toolbox\sdt\openfem;',...
   matlabroot,'\toolbox\sdt\sdtdemos;',...
  

• edit sdt/info.xml so that the help_location key contains the proper entry (otherwise the MATLAB doc command will not work and you will need to access documentation using sdtweb). Typically the value should be
  

   $toolbox/sdt/help
  

File edits are nominally performed sdtcheck('check') but you need write access to actually edit the files.

Version compatibility. Supported platforms ? Open, extensible ?

SDT version	Matlab version	Platforms
6.0	7.4 (2007a) to 6.5 (R13)	Windows 32 & 64, Linux Intel 32 & 64, Macintosh (G4 & Intel), HPUX
5.3	7.2 (R2006a) 7.1, 7.0, 6.5 (R13)	Windows, Linux Intel 32 and 64, Macintosh, HP700, Solaris
5.2	7.0 (R14), 6.5 (R13), 6.1	Windows, SGI, Solaris, HP700, IBM RS6000, Linux Intel, Macintosh
5.1	6.5, 6.1	Windows, SGI, SGI64, Solaris, HP700, IBM RS6000, Dec Alpha, Linux Intel, Macintosh
5.0	6.5, 6.1, 6.0	Windows, SGI, SGI64, Solaris, HP700, IBM RS6000, Dec Alpha, Linux Intel, Macintosh

Almost all the SDT code is .m files which are clearly open and extensible. Significant documentation efforts are made to detail the toolbox architecture so that you can easily extend it (add new elements, ...).
