You can set physical options for selected objects to override the default physical options.
There are two different interfaces for specifying physical options for individual objects, both of which are accessible through tabs on the object's property sheet. Changes made on either of these tabs will be reflected on the other:
Physical Options (Common) – this tab is displayed by default (along with the Partition tab, if applicable), and lists the most commonly-used physical options in the format of a standard property sheet tab. You can enter values for the necessary option parameters and click OK
Physical Options (All) – this tab is hidden by default, and lists all the available physical options for the object in a tree format. To display this tab, click the Property Sheet Menu button and select . Follow the procedure in Defining Default Physical Options, to modify the appropriate options.
