Draglib Download Page

Draglib files on this page are open-source cross-section libraries compatible with Dragon Version 3.06 (and upward) and Dragon Version 4. They can be downloaded from this page and laid in a directory structure similar to

Open-source libraries are available in various formats. Libraries were processed using NJOY 99. Np-237 in Jeff 3.1 libraries was taken from Jeff 3.0. Open-source Draglibs are available with the following energy meshes:

• XMAS-172 is a legacy energy mesh defined conjointly by UK and France. It is used in many countries.
• SHEM-281 is an energy mesh defined by Alain Santamarina at CEA (France). It is used in REL-2005 computational schemes adopted at CEA and EDF.[1]
• SHEM-361 is an energy mesh defined by Alain Santamarina and Alain Hébert and and obtained by refining the group structure of SHEM-281 in the resolved energy domain, above 22.5eV.[2]
• SHEM-295 is an energy mesh defined by Alain Hébert at École Polytechnique de Montréal. Is is obtained from SHEM-361 by defining coarse energy groups between 4.6 and 22.5 eV.
• SHEM-315 is an energy mesh defined by Alain Hébert at École Polytechnique de Montréal. Is is obtained from SHEM-295 by refining the energy groups between 1 and 10 keV and by moving some energy limits so that SHEM-315 is a superset of the ERANOS 33-group mesh.

• Little-endian libraries. These libraries are used on Intel, AMD and Alpha systems.

• ASCII-formatted libraries. These libraries are available in LCM-export format, as produced by PyNjoy. To convert a library to binary, you have to follow the instructions from the PyNjoy tutorial (PDF).

• The following PyNJOY data files are provided in case you want to run NJOY-99 via the PyNJOY system and make a Draglib by yourself. Processing a single evaluation for a single energy mesh takes around 10 hour of CPU time. The above datafiles are creating the Draglib on the /tmp directory of the workstation, in order to save CPU resources.
