GGU-2D-TRANSIENT: "(Potential or source) In section" menu item

After going to this menu item, time-dependent potentials or sources can be defined or deleted for several FEM nodes simultaneously by assigning them a polygon course. Define the section by clicking four points in an anti-clockwise direction. Use the right mouse button to undo. The definition refers to all nodes within the quadrilateral. If the boundary condition is to be applied to all planes, activate the "For all" check box. If the "Define" button is pressed the same dialog box opens as for "Time BC/Point potential or source".
