                          ERROR - Can't Edit Mech Contours

                          Authored by Aaron Schedlin July 21st, 2023 3549 views 0 likes KB2075959

                          Error

                          Not able to normally edit contours in Mechanical.

                          Expected Behavior:

                          Your browser does not support HTML5 video.

                          Software & Version

                          Mechanical 2023 R1

                          *This documented instance of this error occurred in this version but is not necessarily limited to this version.

                          Description/Cause

                          This typically occurs on a laptop with Nvidia RTX graphics cards and recent drivers. 

                          Solution

                          Solution 1: Update to 2023 R2

                          Go to Current Release (ansys.com) to download 2023 R2 or if you do not have an Ansys account, contact support@simutechgroup.com to request a link. You will then need to manually add this environment variable: ANS_USE_OPENGL_LEGEND_EDIT. The variable value needs to be set to 1.

                          Solution 2: Roll Back Drivers

                          Rollback updated driver or uninstall and reinstall driver from Device Manager:

                          Install the Nvidia RTX driver that last worked. Version 517.88 has been tested.

                           
                           

                          Solution 3: Edit Contours Blind

                          If using the new driver, it does not show a live edit. If you right click on the value and choose Edit, you can input a value then hit Enter. See example below:

                          Your browser does not support HTML5 video.
