@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), of the scaled Jacobian and/or of the isotropy measure. Statistics are printed and if asked a Pview is created for each measure. The plugin hides elements for which the measure mu > 'Hidding threshold', where mu is the isotropy measure if asked otherwise the scaled Jacobian if asked otherwise the Jacobian determinant.@*
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 > 'Hidding 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 informations only on validity while the other measure gives also informations on quality.@*
Warning: the scaled Jacobian is experimental for triangles, tetrahedra, prisms and pyramids. Computation may take a lot of time for those elements!@*
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:@*
@*
- Jacobian determinant = @{0, 1@}@*
- Scaled Jacobian = @{0, 1@}@*
- Isotropy = @{0, 1@}@*
@*
- Hidding threshold = [0, 1]: Does nothing if Isotropy == 0 and Scaled Jacobian == 0. Otherwise, hides all element for which min(mu) is strictly greater than the threshold, where mu is the isotropy if Isotropy == 1, otherwise it is the Scaled Jacobian. If threshold == 1, no effect, if == 0 hide all elements except invalid.@*
- IGE measure = @{0, 1@}@*
@*
- Draw PView = @{0, 1@}: Creates a PView of min(J)/max(J), min(scaled Jac) and/or min(isotropy) according to what is asked. If 'Recompute' = 1, a new PView is redrawed.@*
- ICN measure = @{0, 1@}@*
@*
- Recompute = @{0,1@}: If the mesh has changed, set to 1 to recompute the bounds.@*
- Hidding threshold = [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.@*
@*
- Draw PView = @{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.@*
@*
- Dimension = @{-1, 1, 2, 3, 4@}: If == -1, analyse element of the greater dimension. If == 4, analyse 2D and 3D elements.
