However, pure mesh untangling methods focus on untangling inverted elements and often result in meshes with poor element qualities.
We focus on tangled meshes with poor element qualities.
For highly tangled meshes with skinny elements, interior vertices are often highly constrained to move due to geometric constraints.
We tested the ability of our proposed algorithm to generate high-quality meshes with no inverted elements on several extremely large boundary deformations.
The latter generation of meshes included the light weight meshes with
larger pore size resulting in smaller interface between the mesh and surrounding tissues, low weight per area, greater elasticity and a lower burst pressure.
Polypropylene meshes are monofilament, non-absorbable, inert, sterile and porous with thickness approximately 0.44mm while polyester meshes are non-absorbable, polyfilament meshes with
properties mimicking polypropylene.
The 3D mesher is now more tolerant of poor surface meshes with
long triangle edges and also reduces the total number of tetrahedral elements required to represent a model, thus allowing a 3D analysis to be completed faster.
Hexcore meshes combine the automation and geometric flexibility of tet/hybrid meshes with
greatly reduced cell counts in many applications.
Many commercial mesh generators produce meshes with
elements that are skewed, warped, and have large aspect ratios.
