SCOPT,
TempDepKey
, MappingKey
Specifies System Coupling options.
TempDepKey
Temperature-dependent behavior key based on the convection coefficient:
YES
—
A negative convection coefficient, -
N
, is assumed to be a function of temperature and is determined from the HF property table for materialN
(MP command). This is the default behavior.NO
—
A negative convection coefficient, -
N
, is used as is in the convection calculation.
MappingKey
Controls whether midside nodes of higher-order elements are used for mapping on System Coupling interfaces:
YES
—
Both corner and midside nodes are used (default).
NO
—
Only corner nodes are used.
Notes
By default in the Mechanical APDL program, a negative convection coefficient value triggers temperature-dependent behavior. In some one-way CFD to Mechanical APDL thermal simulations, it is desirable to allow convection coefficients to be used as negative values. To do so, issue the command SCOPT,NO.
