If Type is set to Force, then the dialog will look as shown below.
Forces on geometric entities (curves, vertices, surfaces) are on a per entity basis. For example, when you select two surfaces, the magnitude of that load will be applied to both surfaces resulting in a total load of two times the input magnitude. When Total Force is checked for the load on selected two surfaces, then it will be applied to both surfaces by distributing the input magnitude.
Forces can have a Variable Load Definition as well as custom display properties such as color, size, and density.
