That is great - for reference and for anyone using APDL for thermal heat transfer, attached is a the apdl input for NAFEMS benchmark T4 (convection heat), where the block has a convection on the right and top edges (SFL command). A fixed temp. is applied on the bottom edge, while the left edge is insulated. The target temperature at x=0.6 and y=0.2 is 18.3 degrees C, which is close to what we get. Hope this helps anyone:
