HMath-3030: Working with HyperMath

In this tutorial, HyperMath files (*.hml) will be executed in Batch Mode. The output from the files will be written to text files.

Step 1: Launch HyperMath.

1.	From the Start menu, select All Programs > Altair HyperWorks > HyperMath.

This launches HyperMath in the HyperMath GUI. Notice that by default, a file named Untitled1.hml exists in the Editor window.

Step 2: Open and run the files Tutorial_Matrix_noplot.hml and Tutorial_RK45_noplot.hml in HyperMath.

1.	From the File Browser, click on the open file icon, , and browse to the hmath folder. Click OK.

2.	From the list of files in the File Browser, left-click to select the file Tutorial_Matrix_noplot.hml. Drag and drop the file in the Editor window.

3.	Click the Run File button, , to run the file. Notice the output which is printed to the Command window.

4.	Again, in the File Browser, locate the file Tutorial_RK45_noplot.hml. Left-click on the file and drag and drop it into the Editor window.

5.	Click the Run File button, , to run the file. Notice the output that is printed to the Command window.

Notice that for both files, there is only text output to the Command window. There are no plots created. Therefore, both of these files can be run in HyperMath in batch mode.

Step 3: Open the command prompt and run the file Tutorial_Matrix_noplot.hml in batch mode.

1.	From the Windows Start menu, select Run. Type cmd and press ENTER.

This launches the command prompt. We will use the command prompt to run the files in HyperMath in batch mode.

2.	At the command prompt, enter the following (replace <altair_installation_dir> with your actual installation location) and press ENTER.

cd <altair_installation_dir>\hwx

This changes the directory to the location in the installation where the hypermath.bat file is located.

Note: On Linux the corresponding folder is <altair_installation_dir>/altair/scripts.

3.	To run the file hypermath.bat, type the following in the command prompt. Do not press ENTER after typing the following command:

hypermath.bat

Note: On Linux the corresponding batch file is hmathbatch

4.	Following the hypermath.bat command, type –f and the path to the file Tutorial_Matrix_noplot.hml. This should look like the following:

hypermath.bat –f <altair_installation_dir>\tutorials\hmath\Tutorial_Matrix_noplot.hml

The –f in the command above is a parameter which is needed before the files are passed to the batch file.

5.	Press ENTER to run the file in batch mode. Notice how all the output is printed to the command prompt. Also, the output is the same as what was printed in HyperMath in the Command window when the file was evaluated.

Step 4: Run the file Tutorial_RK45_noplot.hml in batch mode.

1.	Again, type hypermath.bat at the command prompt. Do not press ENTER after typing this command.

2.	Following the hypermath.bat command, type –f and the path to the file Tutorial_RK45_noplot.hml. This should look like the following:

hypermath.bat –f <altair_installation_dir>\tutorials\hmath\Tutorial_RK45_noplot.hml

3.	Press ENTER to run the file in batch mode. Notice how the output is printed to the command prompt. Also, notice how this output is the same as what was printed in HyperMath in the Command window when the file was evaluated.

Step 5: Run both of the files Tutorial_Matrix_noplot.hml and Tutorial_RK45_noplot.hml in batch mode. Also, have the output from the runs go into a text file.

1.	At the command prompt, type the following:

hypermath.bat –f <altair_installation_dir>\tutorials\hmath\Tutorial_Matrix_noplot.hml <altair_installation_dir>\tutorials\hmath\Tutorial_RK45_noplot.hml >> C:\output.txt

After the –f, the paths to the two files are listed. After the two files, there is a >> with another file listed. This indicates that the output from the two files should be exported to this file. This file needs to be in a folder with write access.

2.	Press ENTER to run the file in batch mode. This time, there isn’t any output written to the command prompt.

3.	Open the file output.txt in a text editor. This file contains the output from the two files that were run in batch mode.
