Symbolic Nuclear Analysis PackageThe 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. Important Notice Concerning Log4J Vulnerability (CVE-2021-44228): The Log4j utility is included in earlier versions of AptPlot and SNAP. We recommend that you promptly delete any earlier versions of AptPlot or SNAP that you may have installed and update to the latest version of this software. AptPlot Version 8.0 which is now included as a plug-in to SNAP Version 4.0.1 was released in October 2021. These versions of AptPlot and SNAP do not include the Log4J utility. |
