2 Conversational tests

As the heading suggests, we present a few test examples which are solved in an easy and interactive fashion. Each test example consists of a series of necessary steps in order to solve the problem under consideration (example: mesh, interpolation, etc.). These steps are executed by calling the relevant preprocessors in the MODULEF library.

We start this chapter by working through an introductory example (section 2.1), where we will guide you through the process of generating the appropriate data files corresponding to each step interactively, executing the corresponding modules, and plotting the results. Having done that, we proceed by briefly presenting three test examples for which the data files exist in the library called TESD.

These data files can be created interactively, by choosing the appropriate option from the main menu which will be displayed on your screen once a preprocessor is activated. This menu will look something like:

 ****************
 EXECUTING APNOPO : ( 2D MESH ) 
 ****************


 -- CREATE THE DATA  =-=  EXECUTE MODULE (DATA EXISTING)  =-=  END  =-=  ?
    -                     -                                    ---

Selecting the CREATE option enables you to generate a data file interactively, as will be shown in detail in the introductory example, by responding to the various questions displayed on your screen. A response has the form of either a keyword, a simple "YES" or "NO", physical data, etc. In the case where a keyword is specified, only the first four letters need to be typed. All commands must be typed in capitals. If an unacceptable response is given an appropriate error message is printed, after which the correct command must be entered.

Listings of the data creation process and the results corresponding to the various preprocessors are included for all the test examples.

Remark: Each test can also be carried out by the general preprocessor TOUTXX. The correspondence between the different preprocessors and the keywords to activate when utilizing TOUTXX is given in the appendix B.
