 These items listed above are not integrated parts of a process but they are saved in separate files which are independent of each other. In this way it is possible to use the same machine configuration in different processes. All example processes use the machine //example.mas// for instance. These items listed above are not integrated parts of a process but they are saved in separate files which are independent of each other.

-When double clicking on an item in the project explorer, a corresponding window opens up, which shows the characteristic data and allows modifying them. The machine, barrel and screw configuration can either be edited directly by clicking on the respective name or icon in the project explorer or in the dialog **Visual machine configuration** (Chapter Enter Machine Parameters and Configuration). This gives an overview of screw, barrel and machine and opens up when clicking on Machine or choosing **Configuration, Configuration editor** within the main menu. This way of changing data which are relevant to the calculation leads to a loss of the current results and the modified settings are available for a new calculation. If data are changed this way and therefore no longer correspond to the original data in the saved files, the unsaved items are marked with an asterisk (*). An exclamation mark marks faulty data. The corresponding data should be checked before the next calculation.+When double clicking on an item in the project explorer, a corresponding window opens up, which shows the characteristic data and allows modifying them.

-By activating a process, a window that contains all information about the results of this process opens up within the empty space. The  figure shows two of such **Process windows**. The process window is divided into two parts. A diagram with the current calculation results (Chapter Diagrams ) which depends on the selection made is placed above the second part a picture of the screw and the barrel configuration. Additionally process parameters (barrel temperatures and material stages) are given in textual form. So far as they are available also the experimental data (Chapter 9) are shown.+By activating a process, a window that contains all information about the results of this process opens up within the empty space.

 SIGMA also allows to define so-called **Batch processes** (Chapter Create a Batch Process), which are like normal processes but they use one machine configuration with several varying process parameters. In case of a batch process the process window shows the process parameters of the base process and a graph for each variation in the diagram. SIGMA also allows to define so-called **Batch processes** (Chapter Create a Batch Process), which are like normal processes but they use one machine configuration with several varying process parameters.

 The upper left frame contains besides the project data tab a tab called **Material**. The material data are fundamental for each calculation and therefore they should be measured and inserted very carefully. SIGMA offers the direct access to the relational database of PAM. PAM is a part of the SIGMA distribution and assists polymer engineers in administrating material data of polymers and in evaluating material parameters of series of measurements. The upper left frame contains besides the project data tab a tab called **Material**.
