CFX-Solver 13 in AIX 5.3
 

CFX-13 is only supporting IBM P5 machine with AIX 5.3 system for the pure solver.
I try to start the CFX-13 solver in batch mode and recieve the following:

bash-3.00# cfx5solve -def test.def

Capability CFX_SOLVER_PHYSICS_MODULE does not exist in the ANSYS licensing pool.
None of the products enabling this capability are available in the specified lic

Details of error:-
----------------
Error detected by routine MAKDAT
CDANAM = LPNQ_OPEN CDTYPE = LOGL ISIZE = 1
CRESLT = FULL

Current Directory : /LPNQ
An error has occurred in cfx5solve:

The ANSYS CFX solver exited with return code 1. No results file has been
created.


But with Windows and Linux mashines, which have the same solver and a graphical interface, the same calculation is run normally. The number of modules in license files on the machines seem to be the same.

What could be the problem?

Looks like you have found a bug in the AIX version. Try manually setting the logical stack size (look in the documentation for how to do this) as the requested stack size of 1 word is clearly wrong.
