struct	_2NearEdges

struct	_CentralCurveOnEdge
	Container of centers of curvature at nodes on an EDGE bounding _ConvexFace. More...

struct	_ConvexFace
	Convex FACE whose radius of curvature is less than the thickness of layers. It is used to detect distortion of prisms based on a convex FACE and to update normals to enable further increasing the thickness. More...

struct	_Curvature

struct	_EdgesOnShape
	_LayerEdge's on a shape and other shape data More...

struct	_halfPlane

struct	_LayerEdge
	Edge normal to surface, connecting a node on solid surface (_nodes[0]) and a node of the most internal layer (_nodes.back()) More...

struct	_LayerEdgeCmp

struct	_MeshOfSolid
	SMESH_ProxyMesh computed by _ViscousBuilder for a SOLID. It is stored in a SMESH_subMesh of the SOLID as SMESH_subMeshEventListenerData. More...

struct	_NodeCoordHelper
	Retriever of node coordinates either directly or from a surface by node UV. More...

class	_Shrinker1D
	Shrinker of nodes on the EDGE. More...

class	_ShrinkShapeListener
	Listener of events of 3D sub-meshes computed with viscous layers. It is used to clear an inferior dim sub-meshes modified by viscous layers. More...

struct	_Simplex
	Simplex (triangle or tetrahedron) based on 1 (tria) or 2 (tet) nodes of _LayerEdge and 2 nodes of the mesh surface beening smoothed. The class is used to check validity of face or volumes around a smoothed node; it stores only 2 nodes as the other nodes are stored by _LayerEdge. More...

struct	_SmoothNode
	Data of node on a shrinked FACE. More...

struct	_SolidData
	Data of a SOLID. More...

struct	_TmpMeshFace
	Class of temporary mesh face. We can't use SMDS_FaceOfNodes since it's impossible to set it's ID which is needed because SMESH_ElementSearcher internaly uses set of elements sorted by ID. More...

struct	_TmpMeshFaceOnEdge
	Class of temporary mesh face storing _LayerEdge it's based on. More...

class	_ViscousBuilder
	Builder of viscous layers. More...

class	_ViscousListener
	Listener of events of 3D sub-meshes computed with viscous layers. It is used to store data computed by _ViscousBuilder for a sub-mesh and to delete the data as soon as it has been used. More...

struct	AverageHyp
	Layers parameters got by averaging several hypotheses. More...
