In all other cells/faces 00032 the damping function becomes 1, since y gets initialized to GREAT and 00033 yStar to 1. 00034 00035 SourceFiles 00036 wallPointYPlusI.H 00037 wallPointYPlus.C 00038 00039 \*---------------------------------------------------------------------------*/ 00040 00041 #ifndef wallPointYPlus_H 00042 #define wallPointYPlus_H 00043 00044 #include <meshTools/wallPointData.H> 00045 00046 // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // 00047 00048 namespace Foam 00049 { 00050 00051 00052 /*---------------------------------------------------------------------------*\ 00053 Class wallPointYPlus Declaration 00054 \*---------------------------------------------------------------------------*/ 00055 00056 class wallPointYPlus 00057 : 00058 public wallPointData<scalar> 00059 { 00060 00061 // Private Member Functions 00062 00063 //- Evaluate distance to point.
