How to apply pressure changed with time for different location in a pipe?

Hello, 

I have a date file for pressure history of a pipe,which is nonuniform and changed with time. Now, I want to apply this load on a pipe model to do dynamic analysis. 

Is it possible to do this without subroutine? Since I have no license for Fortran compiler now.

And how to do this with subroutine?

Thanks,

Huade
