Hello guys!

I am getteing the following error from USER_GET_MESHDATA routine in CFX11. I was not encountring this problem in CFX10.

GCNTRL stacktrace

1 USER_GET_MESHDATA,VolSec

2 USER_GET_MESHDATA,VolSec

3 USER_GET_MESHDATA,VolSec

4 USER_GET_MESHDATA,VolSec ....

the FORTRAN command is as follows

CALL USER_GET_MESHDATA('Volume','Sectors','RETURN','STO P'

& ,CRESLT,NVNOD,pVNOD,CZ,DZ,IZ,LZ,RZ)

Your help in resolving this error is highly appreciated.

Dear Merck,

It seems the documentation for USER_GET_MESHDATA is not (has never been) clear about the use of the parameter ACTION. Data acquisition routines with the parameter ACTION usually must be called twice (I have to think of an exception): once to get the data (RETURN, GET) and a second time to discard (RELEASE, DELETE)..

In ANSYS CFX 11.0, user acquisition routines supporting RETURN and RELEASE for the parameter ACTION must be called in pairs. For example,

CALL USER_GET_MESHDATA(...,.., ..., 'RETURN',...)

Use the stack pointer you got to compute your quantity of interest..

CALL USER_GET_MESHDATA(...,.., ..., 'RELEASE',...)

This way the ANSYS solver know what to do with the space in memory.. The solver will verify the "checksum" of RETURN-RELEASE's

Hope this helps,
