Mapdl.spcnod(encl='', node='', **kwargs)

Defines a space node for radiation using the Radiosity method.



Radiating surface enclosure number. Defaults to 1. If ENCL = STAT, the command lists all enclosure space nodes. If ENCL = DELE, the command deletes all enclosure space nodes.


Node defined to be the space node.


For open systems, an enclosure may radiate to a space node (NODE).

Open systems may be characterized by one or more enclosures (ENCL). Each enclosure may radiate to a different space node (NODE).

For a space node that is not part of the finite element model, specify the temperature using the D command. For the first load step, the space node temperature ramps from the uniform temperature specified by the TUNIF command to the temperature specified by the D command. For subsequent load steps, it ramps from the previous value of the space node temperature. For intermediate load steps, use the SPCNOD,DELETE command and specify the space node temperature again to ramp from the uniform temperature.

For a space node that is part of the finite element model, the temperature is that calculated during the finite element solution.
