Detailed Description

RefineGeometry is an executable block class capable of refine a surface geometry.

RefineGeometry is the object to refine a surface MimmoObject. After the execution of the block the geometry will be refined in function of the refinement method chosen. Beware, the original geometry is permanently modified after refinement.

At the end of the refinement a laplacian smoothing regularization can be performed. Two sub-steps are carried out, a positive and a negative smoothing step, that minimizes the effect on the sharp edges of the geometry. The smoothing is activated by imposing a number of smoothing steps > 0 (default = 0).

Ports available in RefineGeometry Class :

Port Input
PortType	variable/function	DataType
M_GEOM	setGeometry	(MC_SCALAR, MD_MIMMO_)

Port Output
PortType	variable/function	DataType
M_GEOM	getGeometry	(MC_SCALAR, MD_MIMMO_)

The xml available parameters, sections and subsections are the following :

Inherited from BaseManipulation:

ClassName: name of the class as mimmo.RefineGeometry;
Priority: uint marking priority in multi-chain execution;
PlotInExecution: boolean 0/1 print optional results of the class.
OutputPlot: target directory for optional results writing.

Proper of the class:

RefineType: refine method-> 0 Ternary , 1 Red-Green
RefineSteps: (uint) number of refinements. 0 means no refinement.
SmoothingSteps: (uint) number of smoothing steps. 0 means no smoothing.

Geometries have to be mandatorily passed through port.
