Migrating Scenario files

You can open any pre-NX 4 Scenario file in Gateway, Design Simulation, or Pre/Post. All of the data will be migrated; however, you may not be able to access all of it from the Design Simulation application, because Design Simulation contains only a subset of the features available in NX 3 Scenario for Structures.

Note:

All references to “the Simulation application” refer to either Design Simulation or Pre/Post, depending on which one is set up as the default in Customer Defaults.

NX 4 to latest version

Data is migrated seamlessly when you open an NX 4 file in the latest version of NX.

NX 3 to latest version

When you open an NX 3 scenario.sim file in the latest version of NX, the software automatically switches to the Simulation application and opens the following parts:

• scenario_i.prt is the original idealized part file. In previous releases, the idealized part file was implicit and hidden. In the latest version, the idealized part file is a separate, manageable file.

• scenario_f.fem is a new FEM file. The FEM file represents the idealized part geometry as tessellated polygon geometry. It also includes all mesh data.

• scenario_s.sim is a new Simulation file. This is not the same file as your NX 3 scenario.sim file. The Simulation file contains loads and boundary conditions, overrides, and results.

In addition, the software creates a backup of your original NX 3 scenario.sim file. You can retrieve your original data from this backup file if for any reason there's a problem with the migrated data.

Note:

If you're using Teamcenter Integration to migrate data, note that no backup file is created. Teamcenter Integration uses its own mechanisms to track and restore version-controlled data. See Simulation Process Management data model for more information.

NX 2 and earlier to latest version

When you open a pre-NX 3 scenario.prt file in the latest version of NX, the software automatically switches to the Simulation application and opens the following parts:

• scenario_i.prt is the original idealized part file. In previous releases, the idealized part file was implicit and hidden. In the latest version, the idealized part file is a separate, manageable file. This is not your original NX 2 scenario.prt file.

• scenario_f.fem is a new FEM file. The FEM file represents the idealized part geometry as tessellated polygon geometry. It also includes all mesh data.

• scenario_s.sim is a new Simulation file. The Simulation file contains loads and boundary conditions, overrides, solutions, and results.

In addition, the software creates a backup of your original pre-NX 3 scenario.prt file. You can retrieve your original data from this backup file if for any reason there's a problem with the migrated data.
