In CFX 5.6 built in the last step, writting the file. I gote the following massage error. Can any help me about what is it means:

The surface mesh overlaps itself.

Warning: --------

The surface mesh overlaps itself for more than 50 elements. More warning messages will be suppressed

(a) An invalid geometry. Please check that the geometry is

not self-intersecting, and correct if necessary.

(b) THE GEOMETRY MAY BE PARASOLIDS AND IF IT CONTAINS

SURFACES SHARED BETWEEN SOLIDS THE VOLUME MESHER WILL

REPORT THIS FAILURE. Patran does not create a common

surface for Parasolids geometry. Rebuild your geometry

using Patran solids.

(c) Insufficient resolution of the surface mesh in these areas.

Reduce mesh spacing where the intersections occurred

by adding appropriate mesh controls.

(d) The dimensions of the geometry cause this problem.

For example, a model with dimensions of 80000mm

may be reduced to 80m by transforming the solids

using the scale operation and reducing the global

model tolerance accordingly. Three scaling operations

with a scale factor of (0.1,0.1,0.1) will suffice)
