Hello,

what is the difference between "OK" and "ok" on the linear Solution?

You can show on the picture below.

OK - this means the equation has converged very well.
ok - this means the equation has not converged as well as it should.
! - this means the equation has not converged, and the result should not be trusted.

It's all in the CFX guides.

To be more precise:

* indicates that there was a numerical floating point exception and this resulted in the failure of the linear solvers.

F indicates that the linear solvers did not reduce the residuals (that is, the solution was diverging), but the linear solvers may carry on if the divergence is not catastrophic.

ok indicates that the residuals were reduced, but that the degree of reduction did not meet the specified criteria.

OK indicates that the specified convergence criteria for the reduction of residuals was achieved.
