PCONID

Convection property identification number of a PCONV card.

No default (Integer > 0)

MID

Material property identification number of MAT4 card.

(Integer > 0)

Defaults:

If FTYPE = 3, Default = Blank

If FTYPE ≠ 3, No default

FORM

Types of formula used for free convection.

If 0, 10, or 20,

q = H * (T - TAMB)EXPF * (T - TAMB)

If 1, 11, or 21

q = H * (TEXPF - TAMBEXPF)

where, T is grid temperature and TAMB is the ambient temperature.

Default = 0 (Integer: 0, 1, 10, 11, 20, or 21)

EXPF

Free convection exponent.

If FORM = 0, 10, or 20, EXPF = 0.0 for linear convection.

If FORM = 1, 11, or 21, EXPF = 1.0 for linear convection.

Therefore, linear convection formula is:

FTYPE

Convection Coefficient definition type

= 0: the Convection Coefficient is specified on the MAT4 Bulk Data Entry referenced on the MID field

= 3: the Convection Coefficient is specified in the H1 field. The Convection Coefficient on the MAT4 Bulk Data Entry referenced in the MID field is ignored.

No default (Integer: 0 or 3)

H1

Free Convection Coefficient value (for FTYPE=3)

Defines the Free Convection Coefficient Value, if FTYPE=3.

No default  (Real ≥ 0.0)
