Cap (TL) The plug of the thermal liquid port. blockType: AcausalFoundation.ThermalLiquid.Elements.Cap Path in the library: /Physical Modeling/Fundamental/Thermal Liquid/Elements/Cap (TL) Description Block Cap (TL) It is an ideal plug in the thermal liquid network. Through the block Cap (TL) there is no mass flow and energy exchange. This unit can be used to close the ports of the thermal liquid on other units or to set the initial values of pressure and temperature in the unit. Ports Undirected A is a port that nullifies mass and energy flows thermal liquid The port of the thermal liquid, the mass flow and energy exchange through which are zero.
