- Wall, symmetry, periodic and axis boundaries.
- Internal cell zones.
– Fluid, porous media, moving cell zones.
– Solid.
- Internal face boundaries.
- Material properties.
- Proper specification.
Fluent Solver Settings
Lecture Theme:
Fluent requires inputs (solver settings) which tell it how to calculate the
solution. By introducing the concepts of accuracy, stability and
convergence, the purpose of each setting can be understood. Emphasis
will be placed on convergence, which is critical for the CFD simulation.
Learning Aims:
You will learn:
How to choose the solver and the discretization schemes
How to initialize the solution
How to monitor and judge solution convergence and accuracy
Learning Objectives:
You will be able to choose appropriate solver settings for your CFD
simulation and be able to monitor and judge solution convergence
