All Class 3 Error Reports are posted on the customer portal.To minimize the impact of errors on customers between major releases of our products, Ansys occasionally issues service pack releases that include error corrections. A Service Pack is a release delivering little or no new functionality and primarily intended to provide customers with urgently needed bug fixes to existing Major or Focused Release software. The Service Pack may be delivered as a patch to be applied to an existing software installation.When reporting an error, describe it as specifically as possible.
