Using this button you can have Cadmould® 3D-F fill the edit fields above with default values. The temperature values are recommended defaults coming from the material database. If any temperature field should remain empty after you have pressed the "Default" button the database does not provide the corresponding value for the selected material. In a case like this click on the highlighted line in the table on the right to fill the empty fields with the average of the equivalent temperature domain of the material class.
