Apply Flux Loads
Create concentrated fluxes by applying a load, representing fluxes, to element nodes.
Fluxes are load config 6 and are displayed as a thick arrow labeled with the word "flux".
Equations allow you to create force, moment, pressure, temperature or flux loads on your model where the magnitude of the load is a function of the coordinates of the entity to which it is applied. An example of such a load might be an applied temperature whose intensity dissipates as a function of distance from the application point, or a pressure on a container walls due to the level of a fluid inside.
