This application best practice focuses on improving simulation efficiency by using the Coefficient of Convergence method in Ansys Fluent® fluid simulation software. It aims to help you reduce solution time without compromising accuracy.

Learning Outcomes:

After completing this course, participants will be able to:

  1. Understand the concept of Coefficient of Variation (COV) and its role in quantifying CFD solution convergence.
  2. Evaluate convergence using COV in addition to traditional metrics such as residuals and monitor points.
  3. Implement COV monitoring in Ansys Fluent software using Python scripts and UDF-based approaches.
  4. Determine appropriate convergence criteria and stopping points for steady-state and transient CFD simulations.
  5. Reduce computational time and optimize simulation workflows through COV-based convergence assessment techniques.

Prerequisites:

Previous experience using and applying the Ansys Fluent software solver is recommended

Specific training user should read/follow before reading this document:

  • Basic Ansys Fluent software solver functionality
  • UDF 
  • Python

Please note: These training materials were developed and tested in the 2022R1 release.
