Clean Up Your Dirty Geometry
When you import your CAD geometry, it might contain more detail than simulation requires. For example fillets, chamfers, and small holes may be too small to be of any significance to the model but require overly detailed mesh which can increase your file size.
The CAD model may also contain elements, such as sliver surfaces and short edges, that will lead to the creation of badly shaped elements.
Femap remedies these problems with tools that can remove or de-feature insignificant detail, as well as tools that locate and remove bad geometry.
Combined / Composite Curve
Join separate curves together
Combined / Boundary Surfaces
Merge adjoining surfaces
Breaks the surface geometry surrounding a hole into four map-meshable regions.
Uses offset curves to create map-meshable regions around holes.
Create map-meshable regions around complex geometry with multiple curves.
Split large surfaces into smaller ones to help align the geometry and create surfaces that can be map-meshed.
Geometry Clean-Up Demonstration
Results in Action
GustoMSC manufactures offshore drilling vessels that need to withstand harsh working environments, support heavy drilling equipment and offer decades of operation. GustoMSC advocates the use of geometry idealization with the use of beams and plates on hull structures that are much too large to rely on automatic solid mesh generators.
Femap’s geometry idealization tools combined with its application programming interface capability allowed GustoMSC to find and eliminate potential design problems very early on in the design phase.
“Other products focus on automatic meshing of complex mechanical components, which Femap can do, but if you tried to do that with something as big as a hull, your model would be composed of solid elements. Modeling with beams and plates is a better approach, and something that Femap strongly supports.”

Leveraging Your Existing CAD Data
This webinar will look at common problems that occur when attempting to utilize your existing CAD to create an FE model.
You will learn how to deal with:
– Limited CAD access
– Limited geometry cleanup tools
– Incomplete geometry idealization tools
