Ansys with Unix

Ansys can be run in batch mode from either a windows environment like X window or from a text terminal. Batch mode is faster than graphics mode and you have a permanent source file that can be altered or copied. On the other hand, with graphic mode, you get an immediate graphical feedback on your model.
To solve a problem in batch mode, give the command:
```
       ansys  < fname  > out
```
where fname is the name of your source file and out is the name of the output file. There must not already be a file with the name of the second argument. For a quick check, you can omit the second argument.
If you try to start xansys in graphics mode and you get an error message like:
```
    *** FATAL ***                      CP=      1.290   TIME= 12:30:10
    The 3407872 words ( 13.0 MB) of work space (swap space) requested
     is not currently available.  Reenter ANSYS command line with less
     work space requested.
     ***************************************************************
    The above error is non-recoverable by ANSYS
    ANSYS run terminated by the indicated error.
```
it means that there is not enough workspace on your host. Open an xterm on another terminal and run Ansys from there. If you are using my X-window setup, move the cursor to the background and hold down the middle button to get a menu. Move to the bottom of the menu to get a new menu of hosts. Release the button when the desired host is highlighted. Alternatively, give the command give the command:
```
     xon host &
```
where host is the name of the host you want to run on. When you get an xterm on the new machine, first give the xld alias to get a load chart. Then change to your ansys directory and run Ansys.
