The Ducted Assembly Steady State Heat Transfer Software (DASSH) is an open-source tool for calculating temperature and flow distributions in hexagonal, ducted assemblies comprised of wire-wrapped pin bundles. DASSH is intended for use during the design process to provide a rapid assessment of the flow and temperature distribution, especially when assembly designs are in their early stages and not fully developed.
This python version of DASSH is now considered obsolete and has been replaced with the Fortran version of DASSH (herein referred to as DASSH-F).
DASSH-F can be acquired by emailing [email protected] to apply for access.
As such, this repository is no longer actively being maintained or updated.
DASSH requires Python 3.6+. Detailed installation instructions can be found in the user guide.
