The easiest way to work with the analysis tool is to use the diffusive modulus template.

Use the diffusive modulus template

Requirements:

1. you need to select a model from the models menu
2. instentiate it so that it is shown as origin in the LAYOUT FEATURE
3. in the DOMAIN FEATURE materials have to be defined for casting and mold
4. in the BASIC SETTINGS FEATURE proper bounds for the meshing have to be set. (use either a 10% Margin on the 3d diagonal of the bounding box of your part or enter the dimensions of your mold, for example.)
5. (in the OVERVIEW FEATURE you must see your part shown in the color as selected/given in the DOMAINS FEATURE
6. create a proper discretization of your part using the DISCRETIZATION FEAUTURE
