The mappingOptions table, optionally supplied as a parameter to the mm.meshMapping() function, allows to customize the mapping process. The supported flags are:

Attribute	Description	Type	Required	Def. Value
noDataMode	When set to true, activate the noData mode.	Boolean	No	false
noDataValue	If `noDataMode` is true, defines the `noData` value.	Double	No	0.0
noDataEps	If `noDataMode` is true, define the tolerency value on the source mesh boundary.	Double	No	0.0
state	The state number we want to map (cf. GeMA state numbering convention). If setting this value to -1 all states will be mapped	Integer	No	-1
interpType	The interpolator type used to compute the data inside a cell. See(1).	String	No	"default"
interpParam	The parameters associated to the interpolator See(1).	String or Number	No	Depends on interpolator
activeOnly	When set to true, maps data only on the active cells of the destination mesh. No effect if the mapping is done on destination nodes.	Boolean	No	true
info	When set to true, prints informations about the mesh mapping.	Boolean	No	false

When filling this table, keep in mind that only options different from the default are needed. When an option is not present in the table its default value will be used.

(1) Available interpolation types and supported parameters for each one (see the Interpolation methods page for more details):

"default": The default interpolation method, equal to "shape" for element meshes and "idw" with parameter 2 for cell meshes;
"nn": Nearest neighbor interpolation. If an integer parameter 'k' is given, the 'k' closest points will be averaged to return the interpolated value. The default value for 'k' is 1.
"idw": Inverse distance weighted interpolation. The interpolated value is the average of the known values weighted by inverse distance from the interpolation point raised to a power 'p' provided as a real number parameter. If 'p' is absent, a power of 2 is used.
"mls": Moving least squares method. No supported parameters.
"shape": Interpolation using the element's shape function. No supported parameters.
"lshape": Interpolation using the element's equivalent linear shape function. Usefull when dealing with super-parameteric scenarios. No supported parameters.
