Force or moment loads from an external file

Use the Force Load from External File command to extract the nodal forces and moments stored in an sc_h5 result file in HDF5 format and apply them to target nodes in your model. This command lets you choose different load cases in the result file, but creates only one load case at a time in the Simulation Navigator. The sc_h5 result file can originate from a file generated with the Model and Load Pre-processing solution process. For more information on Model and Load Pre-processing, see Model and Load Pre-processing solution process.

In the Force from External File dialog box, you enter the path to the sc_h5 result file, choose the geometry or FE entities on which the load will be applied, specify the subcase ID, and use the Infer Data Set button to query the result file for a valid data set.

The options in the Force from External File dialog box correspond to the fields on the Simcenter Nastran RLOADEX bulk entry.

Note:

When the sc_h5 result file contains multiple load cases and the file originates from an active Model and Load Pre-processing solution, the software can create solution steps for these load cases from a load recipe, and then assign the extracted nodal forces to the solution steps. To do this, right-click the solution and choose Create Load Recipe from Results. Then, right-click the new load recipe and choose New Solution From Load Recipe.

For more information on load recipes, see Load recipes.
