*PCSB
r1, r2
r1: r*8: Substrate bottom convection coefficient
r2: r*8: Sink temperature for substrate bottom convection
*PCSB specifies the convection value and sink temperature for the bottom of the substrate or build plate during each part-level powder bed simulation increment. *PCSB is static, not temperature dependent. *PCSB overides any *CONV value set. Consult Local Convection Temperature Illustrations to see how this card is applied for the powder and no-powder cases.
