Solve a random base excitation event on Linux

This example shows how to solve a random base excitation using a batch file from a Linux shell. To set up the random base excitation, see Create and solve a random base excitation.

1. In the Simulation Navigator, right-click the random base excitation node and choose Solve→Solver Batch File.

2. Navigate to the working directory and open the generated batch file in a text editor.set RBE_HOME=%UGII_BASE_DIR%\nxcae_extras\dynamicsolution\bin %RBE_HOME%\satools.exe D:\Satellite_Dish_Fem_sim1-Solution_1.op2 D:\satellite_dish_fem_sim1-response_dynamics_1-random_base_excitation_1.xml satellite_dish_fem_sim1-response_dynamics_1-random_base_excitation_1 1024

3. Modify the existing lines to use Linux commands and formatting, as follows:setenv RBE_HOME $UGII_BASE_DIR/nxcae_extras/dynamicsolution/bin $RBE_HOME/satools.exe /comm/Satellite_Dish_Fem_sim1-Solution_1.op2 /comm/satellite_dish_fem_sim1-response_dynamics_1-random_base_excitation_1.xml satellite_dish_fem_sim1-response_dynamics_1-random_base_excitation_1 1024

4. Define the SPLM_LICENSE_SERVER, UGII_BASE_DIR, LD_LIBRARY_PATH variables at the top of the file to set the software license server, installation directory, and the satools.exe Linux libraries.The following is an example of the batch file:setenv SPLM_LICENSE_SERVER 28000@vm-nx90-s7 setenv UGII_BASE_DIR /comm/Siemens/ setenv LD_LIBRARY_PATH $UGII_BASE_DIR/nxcae_extras/dynamicsolution/bin setenv RBE_HOME $UGII_BASE_DIR/nxcae_extras/dynamicsolution/bin $RBE_HOME/satools.exe /comm/Satellite_Dish_Fem_sim1-Solution_1.op2 /comm/satellite_dish_fem_sim1-response_dynamics_1-random_base_excitation_1.xml satellite_dish_fem_sim1-response_dynamics_1-random_base_excitation_1 1024

5. Save the batch file.

6. In a Linux shell, navigate to the batch file and execute it.

7. Copy the results to a Windows machine to inspect results in Pre/Post.
