By default, each of snappyHexMesh's phases, i.e castellation, snapping and layer addition will write a complete mesh in time folders. This behaviour can be suppressed by using the option snappyHexMesh `-overwrite` Would you like to suggest an improvement to this page? Create an issue Copyri...

First, to define the temperature boundary condition of the fluid, the equation for the fluid is analyzed using the temperature of the solid. After that, it is repeated until the method of interpreting the governing equation for the solid using the temperature from the fluid converges. The ...

Wall functions were applied in the boundary layer instead of resolving the boundary, which saves computational time. Application of the wall functions required that the first grid near the wall should be located in the log layer. Therefore, the mesh near the wall was refined as shown in Fig....
