EverySim CAD-to-Simulation: Geometry and Meshing Checklist
Prepare CAD geometry for CAE, CFD and FEA in EverySim. Check units, topology, analysis regions and mesh quality; CAD preparation is not the same as general-purpose CAD authoring.
CAD-to-simulation is the preparation of design geometry for an engineering model. EverySim is a simulation platform, not a claimed replacement for every CAD authoring system. Confirm the supported input format and prepare geometry, units and analysis regions before meshing.
A Visually Correct CAD Model Can Still Fail Analysis Preparation
Tiny features, gaps, intersections or an incorrect scale can change the analysis domain or prevent a useful mesh. Simplification should preserve the features that affect the engineering question. Keep the original revision so preparation choices are traceable.
Before Generating a Mesh
Use the current CAD guidelines and test a representative file rather than inferring compatibility from a file extension.
- Confirm units, overall dimensions and coordinate orientation.
- Check whether the intended bodies and boundaries are present.
- Remove unnecessary detail only when its physical effect is understood.
- Inspect the imported geometry and generated mesh before assigning conditions.
Keep Geometry Changes Visible in Design Comparisons
Store a named revision and note each cleanup operation. A geometry change can change surface selection, mesh density and loads, so review those assignments after editing. Unsupported native-project interchange and lossless CAD migration are not promised by this guide.
Questions and answers
Is there software that repairs CAD geometry for simulation automatically?
Yes. EverySim's surface wrapping and geometry healing clean up dirty or incomplete CAD into a watertight shape before meshing, in the browser.
What is automatic mesh generation software?
Software that builds the simulation mesh from geometry without manual meshing. EverySim does this automatically and passes the mesh to CFD, FEA or Vortex analysis.
Which CAD formats can I import?
STEP, IGES, BREP and STL. The Vortex propeller and rotor workflow takes STL.
Can I try it free?
Yes, EverySim has a free start. Sign up and you get 5 credits right away, plus 20 more when you finish onboarding, as a one-time grant. Tutorial runs are free, and credits are only used when a simulation completes successfully; failed and cancelled runs cost nothing.
Does EverySim create CAD models?
No. EverySim prepares and meshes geometry you bring; it is not a CAD authoring tool.
Is EverySim a general-purpose CAD modeling replacement?
This guide describes geometry preparation and simulation. It does not claim parity with a general-purpose CAD authoring or product-lifecycle system.
Does a supported file extension guarantee a mesh will succeed?
No. Geometry quality, topology, units and analysis requirements still need inspection on the actual model.
