FEM Coupling data exchange xml specification.

The look up data file format is an xml specification that can be used to create a multifunctional data file for parameter and data echange from FEM to system simulation <br>Click to close the image

In this paragraph the format forthe xml specification is described. The lookupmD table format isa multifunctional look up table. It includes static parameters as well as one multidimensional look up table. The file format complies to the xml standard and can be created as a text file.

The file format is specified as:

<?xml version="1.0" encoding="iso-8859-1"?>
<datamodel> <data>
<parameters> </parameters>
<table> </table>
</data>

Here the tag <data> is the one that will hold all numerical data. The tag <parameters> is defined as: <parameters>
