spctemp

Radiosity.spctemp(encl='', temp='', **kwargs)

Defines a free-space ambient temperature for radiation using the Radiosity method.

Mechanical APDL Command: SPCTEMP

Parameters:

enclstr

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

tempstr

Temperature of free-space in the reference temperature system. The temperature will be offset by the value specified in the toffst command for internal calculations.

Notes

For open systems, an enclosure may radiate to the free-space ambient temperature ( TEMP ).

Open systems may be characterized by one or more enclosures ( ENCL ). Each enclosure may radiate to a different free-space ambient temperature ( TEMP ).

For the first load step, the space temperature ramps from the uniform temperature specified by the tunif command to the temperature specified by the spctemp command. For subsequent load steps, it ramps from the previous value of the space temperature. For intermediate load steps, use the spctemp,DELETE command and specify the space temperature again to ramp from the uniform temperature.

Reissuing spctemp does not overwrite the previous value. To change the free-space ambient temperature ( TEMP ) between loadsteps, you must issue spctemp,DELETE and then reissue spctemp, ENCL, TEMP.
