*PBCT
r1, r2
r1: r*8: Top surface convection coefficient
r2: r*8: Sink temperature for top surface convection
*PBCT specifies the convection value and sink temperature for the top layer during each part-level powder bed simulation increment. This applies to the top of the part, and if enabled via *+PDR, the top layer of loose powder elements. *PBCT is static, not temperature dependent. *PBCT overides any *CONV value set. Consult Local Convection Temperature Illustrations to see how this card is applied for the powder and no-powder cases.
