Hello,

I am having troubles implementing the Junction Box Example 1: Profile Boundary Condition from the Solver Modeling Guide. Maybe someone has had this problem as well.

How can I add parameters to the variable USER (p.591 in pdf for Relase 16.2)?

What I have tried is using the cfx5cmds on the *.def File to create the ccl file. Then I can edit it with an editor and import it in CFX-Pre.
After that I have a symbol USER in my outline, that I can edit.
Is that the correct way?


My Problem is the following:
When I add this line(as in the guide): Input File = C:\Data\u_profile.dat
it gives the error:
SEVERE
Operation failed. (System exception: ModelRulesImpl::getParam - param not found in object USER: Input File)

It doesnt give an error if I choose a different Name like "Data File", but I think it must be Input File.

Once I enable the junction box in the Solver Control it gives the following error:

ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Signal caught: Segmentation violation |
+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Stopped in routine FPX: SIG_HANDLER |

And if I dissable it, the solver crashes even though I am not using my Routine.

I have used a Junction Box Routine in Example 3: Timestep Control successfully. But that example doesnt use an external data file.

What am I doing wrong?

Thanks in advance for any tips or advice.



P.S. My System is Ansys CFX 16.2 on Win7 64bit

if you choose to write the lines into the CCL File such as the followings, and then it gives the error, I recommend you to enter the lines into the Command Editor dialog box(as the guide says), then press the "process" button to see if there still exists the error.

"USER:
# Location of external inlet profiles.
Input File = /home/user/u_profile.dat
# Printing control. First character should be Y or N
User Printing = Yes
END"

PS: I just also read the junction box routine chapter, but cannot find any input files, models or datas involved in the examples under the directory of Ansys\v*\cfx, could you tell me where to find the files?

I would love to know if someone else also encountered and solved this problem. I had been using CFX 15.0 up until last week where I defined it similarly as OP:

Code:
USER:
  Input File = /home/etc/file.dat
END
But now in CFX 16.2 it doesn't work, giving the exact same error. I did have an older setup where I accidentally typed "Input FIle" (capital I in file) and it didn't have an error. So it seems like Input File is reserved for something in CFX 16.2?

Unfortunately, the parameters under USER: cannot be duplicates of parameters already used by the software.

I do not recall if the user interface gives any warning about the reserved names for those parameters.

Hope the above helps,
