3.8               Error Messages

The software EATOS has been developed to execute complex calculations on the base of a low information level, resp. a low data set of the user. The central point of all calculations is the stoichiometric equation input by the user and the yield. After input of the substance quantities used, e.g., the resulting amounts of coupled products or by-products are determined therefrom. Thereby, the condition corresponding to the reality is fulfilled that the input mass always is of the same size as the output. If inputs of the users do not meet these criteria, an error message points out the cause of the problem. In this manual in the respective chapters corresponding hints to the calculations have been given, so that a solution of the problem becomes comprehensible.

In only a few cases, before calculation the program does not prove completeness of the data. In this way, e.g., a specification of the economic index (CI) is made without error message (or even not made at all), whenever to several substances namely the prices are indicated, but not the amount it is based on. In these cases, the category price will not be considered for the appropriate substances.
