In order to add a distributed force on a flexible body, the force needs to be included in the flexible body H3d during the CMS flex body generation process. The force can be a generic force on a set of nodes, or a pressure load on a set of elements or a thermal loading.

Once the force is available in the flexible body, the force can be scaled with regard to time or a solver function expression using the Properties tab.
