                          ERROR - Failed to export NASTRAN file

                          Authored by Caleb Scharf September 9th, 2022 7177 views 2 likes KB956491

                          Error

                          When using Ansys Mechanical 2021R1, exporting to a NASTRAN file fails with the following message:

                           

                          Error Text:

                          "Failed to export NASTRAN file.  Please refer to the messages for more information." 

                          Description/Cause

                          There is a bug in Ansys 2021R1 that causes this if the customer doesn’t have an Enterprise level license. 

                          Solution 

                          1. Create a System Environment Variable‍ named "ANSYS211_PRODUCT" and set its value to "mech_1" , if you have a Mechanical Pro license, or "mech_2" if you have a Mechanical Premium License.
