Running a random base excitation event from a command line

You can solve a random base excitation event from a command line. The command contains the executable name and path, followed by four arguments.

executable_name op2_file_name xml_file_name project_name flag

• executable_name is the complete path of the satools.exe executable, which is located in the following folder:/nxcae_extras/dynamicsolution/bin

• op2_file_name is the name of the Simcenter Nastran SOL 103 Response Dynamics solution OP2 file.

• xml_file_name is the name of the XML file created by the random base excitation event. To create this file without solving the event, in the Simulation Navigator, right-click the random base excitation node and choose Solve→Write Input File.

• project_name is an arbitrary project name. To display the results under the random base excitation node in the Simulation Navigator, use the XML file name, without the .xml extension.

• flag is an integer code that you must set to 1024.

To run the solution in the Command Prompt window, set the SPLM_LICENSE_SERVER variable to make licensing accessible.

Solver batch file

When you use the Solver Batch File right-click command on the random base excitation node, the software generates the --.bat batch file, which contains the following two lines:

set RBE_HOME=%UGII_BASE_DIR%\nxcae_extras\dynamicsolution\bin%RBE_HOME%\satools.exe op2_file_name xml_file_name project_name 1024

The first line indicates the location of the RBE satools.exe executable. The second line is the command to start the RBE solver for the specified RBE analysis.

Before executing the batch file, modify it as follow:

• Set the SPLM_LICENSE_SERVER variable that points to the license server.

• Set the UGII_BASE_DIR variable that points to the software installation.

• (Linux only) Set the LD_LIBRARY_PATH variable that points to the location of the satools.exe Linux libraries, which are located in the same directory as satools.exe.

Add these variables above the two existing lines.
