@item Plugin(AnalyseCurvedMesh)
Plugin(AnalyseCurvedMesh) analyse all elements of a given dimension. According to what is asked, it computes the minimum of the Jacobian determinant (J), the IGE quality measure (Inverse Gradient Error) and/or the ICN quality measure (Inverse Condition Number). Statistics are printed and, if asked, a Pview is created for each measure. The plugin hides elements for which the measure mu > 'Hiding threshold', where mu is the ICN measure if asked otherwise the IGE measure if asked otherwise the Jacobian determinant.@*
@*
J is faster to compute but gives information only on validity while the other measure gives also information on quality.@*
The IGE measure is related to the error on the gradient of the finite element solution. It is the scaled Jacobian for quads and hexes and a new measure for triangles and tetrahedra.@*
The ICN measure is related to the condition number of the stiffness matrix.@*
(See article "Efficient computation of the minimum of shape quality measures on curvilinear finite elements" for details.)@*
@*
Parameters:@*
@*
- JacobianDeterminant = @{0, 1@}@*
@*
- IGEMeasure = @{0, 1@}@*
@*
- ICNMeasure = @{0, 1@}@*
@*
- HidingThreshold = [0, 1]: Hides all element for which min(mu) is strictly greater than the threshold, where mu is the ICN if ICN measure == 1, otherwise mu is the IGE it IGE measure == 1, otherwise mu is the Jacobian determinant.@*
If threshold == 0, hides all elements except invalid.@*
@*
- DrawPView = @{0, 1@}: Creates a PView of min(J)/max(J), min(IGE) and/or min(ICN) according to what is asked. If 'Recompute' = 1, new PViews are created.@*
@*
- Recompute = @{0,1@}: Should be 1 if the mesh has changed.@*
@*
- DimensionOfElements = @{-1, 1, 2, 3, 4@}: If == -1, analyse element of the greater dimension. If == 4, analyse 2D and 3D elements.

@item Plugin(Crack)
Plugin(Crack) creates a crack around the physical group `PhysicalGroup' of dimension `Dimension' (1 or 2), embedded in a mesh of dimension `Dimension' + 1.

The elements touching the crack on the ``negative'' side are modified to use the newly generated vertices.If `OpenBoundaryPhysicalGroup' is given (> 0), its vertices are duplicated and the crack will be left open on that (part of the) boundary. Otherwise, the lips of the crack are sealed, i.e., its vertices are not duplicated. For 1D cracks, `NormalX', `NormalY' and `NormalZ' provide the reference normal of the surface in which the crack is supposed to be embedded.
