Symbolic Nuclear Analysis Package

The Symbolic Nuclear Analysis Package (SNAP) consists of a suite of integrated applications designed to simplify the process of performing engineering analysis. SNAP is built on the Common Application Framework for Engineering Analysis (CAFEAN) which provides a highly flexible framework for creating and editing input for engineering analysis codes as well as extensive functionality for submitting, monitoring, and interacting with the codes.

Change Log

SNAP 2.6.9 - Released 4/27/2019

  • The model notebook export logic has been updated to prevent a null pointer exception when an attribute document reference does not match an existing attribute.
  • An issue has been resolved that would prevent the automatic execution of functions when no data stores are loaded.
  • An issue was resolved that could cause category objects to be included twice in the Error Report dialog.
  • An error was resolved that caused erratic user interface behavior for job steps with more custom output file keywords specified than automatic keywords provided by the step.
  • The Keywords dialog used to manage custom and inherited keywords for job steps and their outputs has been updated to include parametric keywords and a more clear indication of which inherited keywords have been overridden and which custom keywords are duplicates.
  • The view component MED save logic has been updated to resolve an issue where changes made by importing a view template might not be included in a resulting MED file. This applied only if a file is saved immediately after importing a view template.
  • Resolved an error that prevented models from being compared when model notes were referencing invalid attributes.
