error processing a drag code in command Editor

ROY4 · September 2, 2018, 05:16

Hello everybody,

I would like to enter my own drag model into CFX but when I call it in command editor, I get this Error:

ERROR CCL parser failed with message: Perl Syntax errors detected: Died at (eval 107) line 1.

Does anyone know what's the problem with this? Am I calling the subroutine in a wrong way?

I call it using this command:
! system ("cfx5mkext pt_drag_factor.F") <1 or die;

which I feel is not a correct way to call...
I use Ansys 17.1.
can anyone please help me?

Thank you

No, this is not the correct way to call a fortran routine. Have you looked at the user fortran examples in the documentation?

Dear Glenn, Hi and thanks for your fast response,

I did look through the CFX documentation (Maybe I was not searching the right place?

) and I could not find anything helpful. I'm totally new in this field and have no idea about how to call my drag factor.F file into the Fortran. I changed the pt_drag_factor.F file which is in CFX examples and made a change only in the Schiller-Neumann drag formula. This way of calling the routine was what I found in a tutorial about butterfly valve. However, I know It does not work in my case. I just need to know how to read this drag factor.F.
can you please help me? there are not wide information about CFX programming in net

Look in "User Fortran" in the CFX Modelling manual. (eg: https://www.sharcnet.ca/Software/Ans.../i1317481.html). In fact it even includes an example of how to implement a user fortran drag model.

Dear Glenn,
Thanks a lot for your help. I actually looked for such explanations, but maybe my searching was not complete. I'll check them and if I had further questions I will ask. Thanks a lot again
