ansys.mapdl.core.Mapdl.vfquery#

Mapdl.vfquery(srcelem='', tarelem='', **kwargs)#

Queries and prints element Hemicube view factors and average view factor.

Mechanical APDL Command: VFQUERY

Parameters:

srcelemstr

Elements representing the source radiating surfaces used to query the view factor at the target element(s). If SRCELEM = P, graphical picking is enabled (valid only in the GUI). If SRCELEM = ALL, all selected elements will have their view factors queried. A component name may also be substituted for SRCELEM. Selected elements must be flagged for surface to surface radiation in order to query view factors ( sf, sfa, or sfe with Lab = RDSF). The view factors must have been previously computed.

tarelemstr

Element for view factor query. If TARELEM = P, graphical picking is enabled (valid only in the GUI). If TARELEM = ALL, all selected elements will have their view factors queried. A component name may also be substituted for TARELEM. Selected elements must be flagged for surface to surface radiation in order to query view factors ( sf, sfa, or sfe with Lab = RDSF). The view factors must have been previously computed.

Notes

View factors for each target element will be printed.

An average view factor for all target elements will be computed. (Use get to retrieve the average value).
