Victory Mesh: TCAD mesh generation and solid modeling
Put mesh resolution where your device physics needs it in any 2D or 3D TCAD structure, and build the structure by solid modeling when there’s no process run to start from.
What Victory Mesh does
Victory Mesh meshes, refines and edits 2D and 3D TCAD structures, and builds new ones by solid modeling. What you get is a mesh fitted to the physics your device or extraction simulation has to resolve. It’s the TCAD mesh generation step between process and device. Feed it the raw geometry and doping from Victory Process, or a structure you built here. You get back a mesh refined for device simulation or 3D parasitic extraction, and the refinement runs automatically to the specification you set.
TCAD mesh generation, refinement and solid modeling
Choose the scheme for the structure in front of you, then aim the refinement.
Meshing schemes
Delaunay meshing is the automatic one. It samples without a fixed grid, refines locally, and shapes the mesh around the materials, interfaces and quantities you tell it to prioritize.
Conformal meshing is the one you specify. You get a semi-structured Cartesian grid, refined along each axis separately, so the grid lines sit exactly where you put them.
Refinement
Eight local refinement schemes for Delaunay meshes, some general and some specific to device work: uniform, impurity, junction, iso-surface, interface, shape, approximation distance and quality.
Aim any of them at particular materials or at attributes you define. That’s how a junction gets fine resolution while the substrate under it stays coarse.
Solid modeling
Generate shapes, transform them, join and crop structures, and add analytic doping profiles. It’s enough to build a device from user-defined shapes with Gaussian doping, or to take an existing one apart.
Typical jobs: mirror part of a symmetric device into the whole thing, stretch a compressed device back to its true dimensions, crop or slice out a region for a closer look, swap regions for simulated polycrystalline grains, or bend an existing structure. Anything you build or edit can be remeshed before you simulate it.
Inputs and outputs
In: Silvaco standard structure files (.str), 2D or 3D, and saved states from Victory Process.
Out: to Victory Device for device physics, to Victory RCx for field-solver RC extraction, or to third-party software as .stl or .vtk. You run it from the Deckbuild interface and can check the result in Victory Visual first.
Where it sits in the TCAD flow
Takes in: a structure from Victory Process, or one you build here by solid modeling.
Hands off to: Victory Device, Victory RCx, or a third-party tool.

Three ways in
Evaluating it
Bring the structure whose mesh you don't trust yet. Evaluations use your device data and come with an application engineer assigned to the case. There's no self-serve trial.
Already running it
Downloads sit in Support and Downloads, with the release notes, manuals and worked examples beside them.
Stuck on something
License holders on a current maintenance contract log cases in the support portal and follow each one to resolution there. Include your refinement settings when you raise one.
Victory Mesh questions
What does Victory Mesh do?
Victory Mesh turns a TCAD structure into a mesh a solver can use. It meshes and refines 2D and 3D structures and edits them by cropping, slicing, mirroring or stretching. It also creates new structures through solid modeling, doping included. The result goes to device simulation or field-solver extraction, and it can be remeshed after every edit.
Why does mesh quality matter in TCAD simulation?
The mesh decides what the solver can resolve. Leave it coarse at a junction or an interface and the steep gradient that sets device behavior is averaged out of the answer. A uniformly fine mesh isn't the fix. Local refinement concentrates elements at the features that matter and keeps them sparse everywhere else.
What is the difference between Delaunay and conformal meshing?
Delaunay is automatic and unstructured: it follows the features and refines wherever your chosen materials, interfaces or quantities call for it. Conformal is user-specified, a semi-structured Cartesian grid refined per axis, so the lines stay where you set them. The eight local refinement schemes belong to Delaunay; conformal is for flows that need a predictable grid.
Can I build a device structure without running process simulation?
Yes. Solid modeling builds the device directly: generate and join user-defined shapes, insert analytic or Gaussian doping, transform the geometry, then remesh and simulate. Use it for a geometry with no process flow yet. It also suits features such as deep etched trenches and textured solar-cell surfaces, which are slow to reach through process simulation.
Which file formats can Victory Mesh import and export?
It opens Silvaco structure files (.str) in two or three dimensions, along with saved states from Victory Process. Victory Device and Victory RCx both take its output directly, for device physics and field-solver RC extraction respectively. For software outside Silvaco, it exports .stl and .vtk.
Can Victory Mesh export to third-party tools?
Yes. It exports .stl and .vtk, both standard formats that software outside Silvaco reads. A structure you've meshed and refined here can leave the Silvaco flow at that point. From there it goes straight to whatever third-party tool your team already uses for its next step.
