EverySim Cloud CFD: Aerodynamic Simulation Evaluation Guide
Plan a computational fluid dynamics (CFD) study with EverySim: geometry, domain, mesh, boundary conditions, convergence and evidence for aerodynamic design decisions.
Computational fluid dynamics (CFD) estimates fluid behavior using a numerical model. EverySim provides cloud-based fluid analysis workflows for engineering design. Evaluate geometry, domain, boundary conditions and convergence before using pressure or aerodynamic forces in a design decision.
Specify a Reproducible Aerodynamic Case
State the speed, fluid properties, orientation and quantity of interest. Define a domain that represents the intended conditions, not only a mesh that fits the imported shape. Record units explicitly so a scale error cannot become a plausible-looking result.
Mesh and Convergence Are Different Checks
A converged numerical iteration does not demonstrate mesh independence. Refine the mesh and compare the engineering quantity across studies while holding other conditions fixed.
- Check domain dimensions and boundary locations.
- Inspect poor-quality cells and refinement near important geometric features.
- Track residual behavior and the stability of forces or other outputs.
- Document a mesh-sensitivity study and the reference used for validation.
CFD Is Not Interchangeable with Rapid Aerodynamics
EveryDrone documents both CFD and a Vortex-method workflow. Their assumptions differ. Select the method from the flow conditions and required output, and review the current theory documentation rather than treating a faster calculation as a universal substitute.
Questions and answers
Can I run a CFD simulation online?
Yes. EverySim runs CFD in a web browser with the computation on cloud infrastructure, so no local install or workstation is needed.
Is there free CFD software I can start with?
You can start EverySim free. 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. Larger or longer runs use paid credits; check current platform pricing.
Which CAD files can I upload?
STEP, IGES, BREP and STL for CFD and FEA. The Vortex propeller and rotor workflow takes STL.
Do I need CFD expertise to use it?
No dedicated analyst is needed to get started: auto-meshing, surface wrapping and geometry healing prepare the geometry, and the AI Assistant guides setup. Results should still be checked against your design assumptions and test data.
How accurate is EverySim CFD?
On a KARI reference case, EverySim results agreed with wind tunnel tests to 97%. Accuracy for your case still depends on setup, mesh and validation evidence.
Does cloud CFD automatically improve accuracy?
No. Hosting changes how computation is accessed. Accuracy still depends on the physical model, numerical setup, mesh and validation evidence.
Where can I discuss an EverySim CFD use case?
Use the EverySim contact page with a description of the geometry, flow conditions and required outputs. Confirm that the current product workflow supports the case.
