Availability Notice


This report describes a developmental patch applicable to TRACE v5.0 that provides the user with additional flexibility in using the existing option graphlevel to specify the list of variables to be included in the graphics output file (XTV). This option is activated from the TRACE input model using newly added Namelist option lists graphCustId and graphCustVar.

This capability, referred to as the XTV-Customize option, is particularly indicated to optimize storage space and/or post-processing memory space for production studies that require large input models, and for research studies that include sensitivity analysis or uncertainty quantification involving very large number of TRACE simulations of a same input file.

The XTV-Customize option is provided in the form of three separate code installation patches applicable to versions v5.0p5, v5.0p4 and v5.0p3 of the TRACE code, respectively.

The developed patch has been verified on the LCLRS Linux 64-bit servers of PSI for a representative sample of test cases, and for the two different TRACE output graphics file formats, namely XTV and DMX. This patch should nevertheless be still considered as developmental. Some recommendations for improvement of the implementation are provided at the end of the report.
