Error during running subroutine with Multiple Processor

Dear all,

My name is Makara, a student from Gangneung-Wonju National University. These days, I am working on the heat transfer analysis of a pavement and in my analysis I also include subroutine of DFLUX and FILM.

When I run my model with Single Processor, there is no error occur. But when I change to Multiple Processor, error occur and analysis is aborted. 

Could you please give me some advice to solve this problem?

Thank you so much in advance for your times.
And I am looking forward to hear from you soon.


Best Regards,Sincerely Yours,
