Default Bingham model in CFX5

Hi everyone,

I found it is hard to realize Bingham model in CFX5 because I can not input shear stress directly, although shear strain can be input into a Fortran subroutine with ease.

Any suggestion is appreciated.

Actually I can realize it using Fortran subroutine. But the problem occurs when I try to run CFX-Solver 5.6. Then I follow the procedures in Tutorial 9 -- Flow through a Butterfly Valve, then I got the similar error message:



+--------------------------------------------------------------------+

| ERROR #001100279 has occurred in subroutine ErrAction. |

| Message: |

| Unable to load symbol inlet_velocity from D:\JW\Simulation\CFX56\tutorials\3\winnt\PipeValve _inlet.dll: The specified procedure could not be found.

| ERROR #001100279 has occurred in subroutine ErrAction. |

| Message: | USER ROUTINE: Wprof could not be loaded. Please check the Library Path, Library Name and Calling Name. For FORTRAN user routines, the Calling Name should be in lower case. | | Writing crash recovery file |

+--------------------------------------------------------------------+

----------------------------------

Error in subroutine GET_SPECVAR :

A recursion problem was encountered when evaluating the expression for "VEL-1_FL1" at the following location: "PipeValve". Please carefully check that the result of your expression does not depend on itself.

GETVAR originally called by subroutine Write_mfloip

+--------------------------------------------------------------------+

| An error has occurred in cfx5solve: | | The CFX-5 solver exited with return code 1. No results file has been created.

End of solution stage.



Anybody can tell me the reasons and what should I do to modify the settings?
