这个边界条件我也没有用过。不过我刚才看了一下源代码。你看一下mapped和TimeVaryingMappedFixedValue的区别：
//- Name of the field data table, defaults to the name of the field
word fieldTableName_;
//- If true adjust the mapped field to maintain average value
Switch setAverage_;
//- Fraction of perturbation (fraction of bounding box) to add
scalar perturb_;
//- Interpolation scheme to use
word mapMethod_;
//- 2D interpolation (for 'planarInterpolation' mapMethod)
autoPtr<pointToPointPlanarInterpolation> mapperPtr_;
//- List of boundaryData time directories
instantList sampleTimes_;
//- Current starting index in sampleTimes
label startSampleTime_;
//- Interpolated values from startSampleTime
Field<Type> startSampledValues_;
//- If setAverage: starting average value
Type startAverage_;
//- Current end index in sampleTimes
label endSampleTime_;
//- Interpolated values from endSampleTime
Field<Type> endSampledValues_;
//- If setAverage: end average value
Type endAverage_;
//- Time varying offset values to interpolated data
autoPtr<Function1<Type>> offset_;
Example of the boundary condition specification:
\verbatim
<patchName>
{
type mapped;
fieldName T;
setAverage no;
average 0;
interpolationScheme cell;
value uniform 0;
}
\endverbatim
TimeVaryingMappedFixedValue看起来就是附加了开始sample的时间以及结束sample时间的mapped边界条件。在时间之外，就是fixedValue。你核实下。
