Simulation Toolbar - Thermal Loads The Thermal Loads category provides tools for defining temperature, convection, heat flux, heat power, and radiation conditions for the active thermal study. Button Tool Tip Purpose Temperature Defines a temperature on the selected entities for the active study. Convection Defines a convection on the selected entities for the active thermal study. Heat Flux Defines a heat flux on the selected entities for the active thermal study. Heat Power Defines a heat power on the selected entities for the active thermal study. Radiation Defines radiation on the selected entities for the active thermal study.
