Principles of FlowVision testing

All the tests are stored in a Test base. The base is structured in a special way. The tests are documented according to the developed standard. Once a new option or model is implemented in FlowVision, the corresponding tests are produced and added to the Test base. All the options and models are tested before issuing each release or update of the software.

Tested options and auxiliary algorithms

• Geometry import
• Grid generation
• Solving systems of algebraic equations
• Visualizing results
• All the interface parametres and settings
• Substance database

The implemented options and algorithms are tested both separately and in different combinations.

Tested models of physical processes

FlowVision 2.xx.xx:

• Solid material
• Laminar flow
• Incompressible fluid
• Weakly compressible fluid
• Fully compressible fluid
• Porous medium
• Free surface
• Gas-phase combustion
• 2-phase combustion
• Turbulence models
• Surface-to-surface radiation
• Gas radiation
• Particles
• Gap model

FlowVision 3.xx.xx (-HPC):

• Heat conduction and convection
• Motion of Newtonian fluid
• Turbulence models
• Free surface
• Gap model

Testing a physical model includes testing all the appropriate boundary conditions.

Test projects

Projects for testing user options and auxiliry algorithms are normally simple (simple physics, coarse grids, etc.).

Projects for testing physical models and boundary conditions are subdivided into qualitative and quantitative. The qualitative tests demonstrate capability of the software to model a given flow or physical process (validation). The quantitative tests imply comparison of calculations with known analytic solutions, empirical correlations, and available experiments (verification). This section provides several quantitative test cases.
