CTH support is provided for contractual, distribution and activation tickets as soon as possible. CTH is utilized for a multitude of important missions and while it is our desire to support each of these to the best of our abilities, CTH is managed as a full cost recovery organization and as such, development/support is contractually obligated to align with existing funded efforts. Other support tickets will be assessed on a case-by-case basis dependent upon ongoing development and/or existing support agreements.

To ensure adequate staffing and resource levels beyond this, separate agreements may be pursued. If your organization is interested in partnering in an expanded development/support capability please contact with your inquiry.

WARNING: While this system is contained on internal SNL servers email exchanges, over the course of a ticket, it may leave this environment. Please DO NOT INCLUDE OUO on tickets including outside entities. – General support for questions about running CTH, bug reports, missing or incorrect documentation or suggested improvements to the software. – Questions and correspondence on installation of CTH.

NOTE: The "view request" option mentioned on the ticket system is currently only available from within Sandia’s restricted (internal) network. For offsite customers respond to tickets emails as normal and they will link with the generated tickets.
