Random base excitation output files

When you solve a random base excitation (RBE) event, the following output files are written in the working folder.

--.xml

Stores the input information for the random base excitation solver. Before you launch the solver from a command line, you can modify the input XML file with a text editor to change the settings.

--.log

Stores RBE solution messages, warnings and errors. You should always review the log file after performing a solution.

--.sum

Stores a summary of the random base excitation event settings and contains a table listing all output requests in an easy to read format.

--.op2

Stores geometry and the most requested results in SORT1 and SORT2 formats. This is the master results file and it is always written unless an error occurs.

--.bun

Stores additional results. This is the companion results file that contains magnitudes (displacements, velocities, accelerations), principal stresses and strains, and margins of safety, which cannot be written to a Nastran binary file. It is automatically loaded with the OP2 file.

--.bat

Contains commands to execute the RBE solver from a command line. This file is generated when you use the Solver Batch File right-click command on the random base excitation node. For more information, see Running a random base excitation event from a command line.

Text output results files

Store requested results in text format when you set the Text Output customer default on the Simulation→Pre/Post→Simcenter 3D Response Dynamics→Random Base Excitation tab in the Customer Defaults dialog box. Each file contains one type of result.FileResults**--_acce.outAcceleration results--_disp.outDisplacement results--_velo.outVelocity results--_spcf.outSingle-point constraint (SPC) force results--_mpcf.outMultipoint constraint (MPC) force results--_gpfe.outGrid point force results--_stra.outStrain results--_stre.outStress results--_elfo.outElement force results--_msfy.outFailure metric results--_cfai.out**Laminate failure metric results
