SF command (Electro-Thermal Analysis)

[Simulink81]

Hi,
i'm trying to solve a problem like

http://www.kxcad.net/ansys/ANSYS/ansyshelp/coustrutherelecexamp.html

(Electro-Thermal Microactuator Analysis)but i don't understand how i must use sf command:
asel,s,area,,1
nsla,s,1 ! Thin arm and flexure
nsel,r,loc,x,d8,d8+d4+d5-d6
nsel,r,loc,y,0,d1
sf,all,CONV,-5,Tblk
nsla,s,1
nsel,r,loc,x,d8,d8+d4
nsel,r,loc,y,-(d3+d7),-d7
sf,all,CONV,-5,Tblk
mpdata,HF,5,1,22.4,69.3,76.1,80.5,83.7,86.0
mpdata,HF,5,7,87.5
sf,all,CONV,-5,Tblk
If Lab = CONV, VALUE is typically the film coefficient and VALUE2 (below) is typically the bulk temperature. If VALUE = -N, the film coefficient may be a function of temperature and is determined from the HF property table for material N [MP]. The temperature used to evaluate the film coefficient is usually the average between the bulk and wall temperatures, but may be user-defined for some elements.
How can i calculate HF coefficients?
Best regards!!!

You don't need to calculate what's the film coefficient value, since it's interpolated from the temperature dependent HF table that's defined.
