There is an unique existence that the user procedure method is the only way to apply user's model when estimating molecular diffusivity coefficient. So I compiled the fortran code with the template and Build the .dll file followed the hints of the procedure manager. Now, the specification indicator is green, but running with a trouble. The massge told that SUIF55_pUgAvMW is not found in the user dll file gusersub. Why is there a missing on the average molecular weight estimation? This estimation I have not ever specified.

Another trouble is the failure of discomposing some sub groups after the two subruotine, pUgAvMW and SUIF55_pUgAvMW, have been build into gusersub, too. Is there some wrong in my operation? Thanks for your assistance.
