Prepare Your Simulations Systematically

with Simuneer and Cadence Fidelity® CFD Software

From setup to result

Pre-Processing is the foundation of your flow simulation. This includes steps such as: Import CAD, clean up geometries and create a robust mesh.

The goal: a clean model that delivers reliable results from the very first run. We achieve this with clear standards, our expertise and the flexible tools of Fidelity CFD.
Image description

Straight from CAD to simulation

Import all common native and discrete CAD formats directly into Fidelity CFD. Powerful CAD manipulation tools bring your models into shape in minutes — without tedious iterations with the design.

With clever software modules such as Fidelity® Autoseal, you can close complex holes automatically and make geometries instantly meshed.
Image description

Mesh at its best — even with ‘dirty CAD’

Structured or unstructured, (partially) automated or manual — in Pre-Processing with Fidelity CFD, you retain control when it comes to networking. All processes can be combined as required.

Your advantage: You always get the best mesh, no matter how complex your geometry is.
Image description

Templates, automation and hands-on support

Set up once, use always: Create templates without any programming effort. Then all you need to do is load the geometry and start the workflow (meshing → simulation → post-processing).

Do you want access to all functions? No problem thanks to the Python API. Either way, our professional support is there for you.

Fidelity CFD Platform

Specialized modules for Pre-Processing

Autoseal — Pre-Processing (CAD)

Autoseal automatically closes any complex holes in the geometry, preserves geometry details and immediately delivers meshable, closed volumes.

  • Closes holes due to missing components and unclean CAD
  • 1-Click Solution — without tedious manual work
  • Shortens (the) preparation time of complex models from days to hours

Autogrid — Meshing (structured)

Autogrid is the fully automatic, structured multi-block mesh generator for turbomachinery: It networks pumps, fans, compressors and turbines with any number of stages and delivers high-quality, solver-friendly meshes for optimum CFD results.

  • Guided wizard sets optimum network settings
  • Geometry features such as cavities, fillets and side wall contouring
  • Scripting capability integrates Autogrid seamlessly into your process chain

Hexpress — Meshing (unstructured)

Hexpress is the unstructured mesher in Fidelity®: It generates hexahedron-dominant or purely hexahedral meshes for complex geometries.

  • Unclean CAD can be meshed directly without time-consuming preparation
  • Thanks to efficient parallelization, solver-friendly, high-quality networks are created in a short time, even with high cell counts
  • Ideal for fast Pre-Processing workflows

Stitch — Voronoi Meshing (LES)

Specially optimized for LES, Stitch generates Voronoi-based volume meshes with isotropic resolution — ideal for the precise resolution of complex turbulent structures.

  • High grid quality thanks to orthogonal cell geometry
  • Flexible topologies: polyhedral or hexadominant cells depending on the background distribution
  • Robust with complex geometry due to decoupled surface and volume length scales
  • Massively scalable for large models and HPC environments
