Running a Laminate Dynamics solution process from a command line

You can run a Laminate Dynamics solution process from a command line. You run the command from the working folder of your dynamic simulation. 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 full path to 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 Real Eigenvalues solution OP2 file.

• xml_file_name is the name of the XML file created by the laminate dynamic random or sine event. You can create this file without solving the event when you right-click the event node in the Simulation Navigator and choose Solve→Write Input File.

• project_name is an arbitrary project name that is used in the random or sine OP2 file name. However, in order to display the results under the random or sine event node in the Simulation Navigator, you should use the XML file name, without the .xml extension.

• flag is a number that determines the type of processor. Use 16 to specify the random processor and 128 to specify the sine processor.

Licensing must be accessible in order to run the solution in the Command Prompt window.

Windows Command Prompt example

Define an environment variable that points to the nxcae_extras/dynamicsolution/bin folder where this software is installed. For example:

set SCLC_HOME=D:\Siemens\UgsNX-9.0(64)\nxcae_extras\dynamicsolution\bin

In a Command Prompt window, navigate to the working folder of your dynamic simulation folder, and then enter one of the following commands:

%SCLC_HOME%\satools.exe ssim1–sol_103.op2 sim1–DynamicSim1–Random1.xml sim1–DynamicSim1–Random1 16

%SCLC_HOME%\satools.exe ssim1–sol_103.op2 sim1–DynamicSim1–Sine1.xml sim1–DynamicSim1–Sine1 128

Linux Bash Shell example

Define an environment variable that points to the nxcae_extras/dynamicsolution/bin folder where this software is installed. For example:

setenv SCLC_HOME /comm/ugnx/ugnx90/nxcae_extras/dynamicsolution/bin

In the working folder of your dynamic simulation folder, use one of the following command lines:

$SCLC_HOME/satools.exe ssim1–sol_103.op2 sim1–DynamicSim1–Random1.xml sim1–DynamicSim1–Random1 16

$SCLC_HOME/satools.exe ssim1–sol_103.op2 sim1–DynamicSim1–Sine1.xml sim1–DynamicSim1–Sine1 128

If the supplied shared libraries are not found, you need to add the specified directory to the library lookup path as follows:

setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/comm/ugnx/ugnx90/nxcae_extras/dynamicsolution/bin
