CFX 5.6 the surface overlape itself
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.
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)
