On the Loads tab, there are several features available for applying internal and external loads, such as force, pressure, and temperature.
How ICEM CFD treats the load depends on how the load is applied - to a curve, a surface, or a mesh. In all cases, the load information is not calculated until you are creating the output files for one of the supported "Common Structural" solvers: Ansys, Autodyn, LS-DYNA, ABAQUS, or NASTRAN. That is, the output file is generated thru the Solve Options Tab, and at this time, the loads will be written out according to the selected solver's published format.
