Meshing Tips
Compatible meshing is more accurate than incompatible
meshing in the interface region. Requesting compatible meshing can cause
mesh failure in some cases. Requesting incompatible meshing can result
in successful results. You can request compatible meshing and select Remesh failed parts with incompatible mesh
so that the software uses incompatible meshing only for bodies that fail
to mesh.
Check for interferences between bodies when using
a compatible mesh with the curvature-based mesher. If you specify a bonded
contact condition between bodies, they should be touching. If interferences
are detected, meshing stops, and you can access the Interference
Detection PropertyManager to view the interfering parts. Make sure
to resolve all interferences before you mesh again.
If meshing fails, use the Failure
Diagnostics tool to locate the cause of mesh failure. Try the proposed
options to solve the problem. You can also try different element size,
define mesh control, or activate Enable
automatic looping for solids.
The SolidWorks Simplify
utility lets you suppress features that meet a specified simplification
factor. In the Simulation study tree, right-click Mesh
and select Simplify Model for Meshing
. This displays the Simplify
utility.
Simplification of geometry
can alter stress results significantly.
It is good practice to check mesh options before
meshing. For example, the Automatic transition
can result in generating an unnecessarily large number of elements for
models with many small features. The high quality mesh is recommended
for most cases. The Automatic looping
can help solve meshing problems automatically, but you can adjust its
settings for a particular model. The Curvature-based
mesher automatically uses smaller element sizes in regions with
high curvature.
To improve results in important areas, use mesh
control to set a smaller element size. When meshing an assembly with a
wide range of component sizes, default meshing results in a relatively
coarse mesh for small components. Component mesh control offers
an easy way to give more importance to the selected small components.
Use this option to identify important small components.
For static studies, you can
use the h-adaptive method to refine
the mesh automatically.
