Why do I get the warning below when combining cdb files in ANSYS 7.1?
*** WARNING *** CP= 1.844 TIME= 09:45:48
This ANSYS data base has both Smooth and Web based Data. There are
possible problems with using this data.

In ANSYS 5.4 we introduced some defeaturing tools which required that the geometry be represented by a faceted surface. This has also been called micro-topology and web-based geometry. I believe for one or two releases IGESIN used this form of geometry as the default. Unfortunately this geometry representation is somewhat incompatible with nurbs-based or smooth geometry and combining them has resulted in corrupted databases and boolean failures. That is why we created that warning message, so that users would be aware that they might not be able to do much additional solid modeling with such a model. |
