Global Definitions - Parameters
It is good modeling practice to gather constants and parameters in one place so that you can change them easily. Using parameters will also improve the readability of your input data.
The following parameters will be defined: the maximum element size mh, heat transfer coefficient htc, and terminal current I.
1
In the Model Builder Window, under Global Definitions, select Parameters 1 .
2
In the Settings window for Parameters, locate the Parameters section. You will find some parameters in the table. The parameters are used for building the geometry and they are imported together with the geometry sequence.
In the table, add the following parameters:
