External enforced motion loading

Use this procedure with Model and Load Pre-processing to transform the following time or frequency-dependent loads from the result files from ANSYS, Abaqus, Simcenter Samcef, and other supported solvers into Simcenter Nastran loads:

• Stationary vibration loads (displacements, velocities, or accelerations) at the fluid-structure interface.

• Vibration loads (displacements, velocities, accelerations, or forces) at the fluid-structure interface from a rotating mesh.

Note:

The vibration loads can have translational or rotational degrees of freedom.

1. Specify an input file to process the external result data.

2. Map the result data from a source to a target mesh.

3. Execute other various data processing operations, such as Time Signal Processing, Time to Waterfall, Export to Binary File, and so on.

4. Execute the Model and Load Pre-processing pre-solver that writes out files in different formats, including a Simcenter HDF5 file.

5. Visualize the results with a preconfigured post-processing view before extracting the vibrations stored in the Simcenter HDF5 file and using them in a Simcenter Nastran solution.Note: The HDF5 file is supported by SOL 108 and SOL 111 solutions.
