An Integral Objective is defined as the integral of a closed form expression of control and solution variables (the latter are given as the solution to the differential equations defined by the multiphysics model) that are either global or available in the domain in question. Hence, its definition is restricted to a set of geometric entities of the same dimension. For integral objectives on points, the integration reduces to a summation.

Enter an Objective expression that is integrated over the geometric entity level in the integral objective.

Specify the settings for the Quadrature used to numerically evaluate the integral in the integral objective: the integration order (default: 4) in the Integration order field and the frame to integrate on (default: the spatial frame), which is selected from the Integrate on frame list.
