Defines the numerical threshold of the selected
parameter that determines the quality of a mesh. For example, if you select the Jacobian ratio as the quality
parameter, and enter 10
here, SOLIDWORKS Simulation diagnoses the mesh elements with a
Jacobian ratio greater than 10 as poor-quality
elements.
A good-quality mesh has a Jacobian ratio
between 1 and 10 and an Aspect ratio less than 5 for most of
its elements (90% and above).
For most models, elements at regions of high curvatures have
higher Aspect and Jacobian ratios. If the elements with the
highest Aspect and Jacobian ratios (larger than 10) are away
from critical areas for the analysis, it may not be
worthwhile to refine the mesh in these areas. However, for
areas that are critical for the simulation, you can refine
the mesh locally to reduce the Aspect and Jacobian ratios
for the poor quality elements and improve the simulation
results.
Depending on the geometry of the model, subsequent levels of
mesh refinement might not improve further the mesh quality
and the simulation results. After each level of mesh
refinement, confirm that the mesh quality plots for Aspect
ratio and Jacobian ratio show fewer poor-quality elements.
In addition, ensure that after each successful mesh
refinement, the simulation results converge to finite
values.
