Saving the Model
Save your work in an es-ice model file using the Write Tool. It is recommended that you create multiple model files during the modelling process, with suitable extensions identifying your work at different stages. This practice allows you to resume from a previous stage, if necessary.
The Write Tool is divided into four sections: the top section sets file-writing options, the second section writes vertices, cells and cell couple definitions, the third section writes database files, and the bottom section saves es-ice model files. Note that when saving an es-ice file, the file-writing options at the top of the panel are not applicable.
To save the model:
•In the Select panel, click Write Data
•In the Write Tool, enter save_es-ice.1-valves and then click
Save
