1 |
Improved solve time for faster execution by decreasing the time to generate the Nastran file. |
|
2 |
Fixed a crash that occurs when right-clicking or double-clicking on a branch of the Model Tree multiple times. |
|
3 |
Fixed an issue in an explicit dynamics analysis that results in GARBLEDFILE error. (See An explicit dynamics analysis ends with an error "pmo_error: GARBLEDFILE" in Inventor Nastran for details.) |
|
4 |
Resolved issue where Inventor crashed after the analysis (when displaying the results) when the sub-case name included the percent symbol %. |

Resolved issue where none of the dialogs could be opened after using the Check Quality for Mesh tool. (See Inventor Nastran 2025 crashes when using Check Quality for Mesh for details.) |
|

Load applied to an edge now creates a uniform distribution. (See Force applied to an edge is an approximation in Inventor Nastran for details.) |
