This document discusses a meshing tool called Hexpresso that can generate hexahedral meshes for simulations in a fast and automated way. It summarizes that Hexpresso can mesh models with one click, supports adaptive meshing, and can mesh models based on masks and process parameters. It claims Hexpresso can reduce the time spent on meshing tasks by around 80% compared to standard methods.

1. hex meshing in a jiffy

2. One click meshing
100% hexahedral meshes

5. Mask to mesh
Automated meshing of a
micromirror array

6. Schematic to mesh
Automated Hexahedral Meshing of the Structure

7. Automated refinement of high stress areas …
Stress relief curves are identified and meshed

8. Apply mask transforms on the fly…
Generate parametric meshes for each of the process corners
Mask transforms such as
lateral and rotational misalignments,
offsets (mask grow/shrink) can
be applied on the fly…

9. Benefits…
High quality meshing Parametric meshing
All hexahedral mesh creation Change device parameters without
remeshing
Drastically reduce your
design time Mask transformations
80% savings compared to standard Easily account for process corners
methods including mask misalignments and
mask offsets
Auto mesh refinement
Speed
Identifies and refines areas of high
stress Typical meshes in under 1 minute
