User Fortran script failures

honcho62 · January 11, 2016, 08:01

Hi everyone,

I'm trying to implement a user subroutine that applies momentum at specific locations in the mesh. I'm using the MomentumSource1.F and ucf_template.F as a guide.

One of the things I need are matrices, I've done a little bit of fortran tutorials before starting on this but they seem pointless.

For instance I thought I should define a matrix like

real dimension(4,4) :: MyMatrix

or

real (kind=ikind),dimension(4,4) :: MyMatrix

but when I compile it using cfx5mkext and pgf95 it says there is a syntax error in this line. Are there different rules for these types of code?

In my Fortran code I define arrays as

Code:

 REAL mk(3,10)

Im not sure if higher dimensions work differently, but this works as intended.

thanks for the answer.

the definition actually does work but you need to put the comma after REAL. So that's solved I guess.
