MESH / 033
CFD Mesh Cell Count, Memory & Cost Estimator
Estimate the order of magnitude of mesh size and computational workload before committing to a refinement strategy.
Use the calculation to challenge the CFD setup.
Mesh planning is a resource decision as well as a numerical decision. A rough cost model helps compare refinement strategies before generating several expensive meshes.
Define the reference scale. Use values that represent the actual engineering problem.
Calculate transparently. The tool exposes the governing relation and intermediate outputs.
Compare with the solver. Look for inconsistent definitions, units or modelling assumptions.
Test sensitivity. Important CFD conclusions should not depend on one arbitrary input or discretization choice.
Move from calculation to diagnosis.
Use the result as a benchmark, then follow the relevant Technical Case or consulting capability when the actual CFD model needs deeper judgement.
