Unknow write type "boundaryData" in surfacesSampling format
I used surfaceFormat boundaryData (A form that can be used with timeVaryingMapped boundary) in surfacesSampling to have point information. I can still find it here :https://www.openfoam.com/documentation/user-guide/userse21.php.
In openFoam4.1 under Ubuntu system, "boundaryData" is a unknow type. I cannot figure it out.
Furthermore, "boundaryData" and "foamFile" don't give the same number points. The boundary conditon "timeVaryingMappedFixedValue" prefers the point file outputed from "boundaryData" which has less point number in the file than the one from "foamFile".
