GetWorstJacobianRatio Method (ICWMesh)

Gets the worst Jacobian ratio for this mesh.

.NET Syntax

Visual Basic (Declaration) 
Function GetWorstJacobianRatio() As System.Double
Visual Basic (Usage) 
Dim instance As ICWMesh
Dim value As System.Double
 
value = instance.GetWorstJacobianRatio()
C# 
System.double GetWorstJacobianRatio()
C++/CLI 
System.double GetWorstJacobianRatio();

Return Value

Worst Jacobian ratio (see Remarks)

Example

Remarks

The data returned by this method is valid only if ICWMesh::Quality is set to swsMeshQuality_e.swsMeshQualityHigh.

Analysis of curved geometry requires a mesh of parabolic tetrahedral elements. With extremely curved edges, placement of the mid-side nodes of these elements on the geometry can distort the elements and the analysis.

The Jacobian ratio calculated at a point inside a parabolic mesh element provides a measure of the degree of distortion at that location. The higher the ratio, the greater the distortion of the element. A Jacobian ratio of 40 or less is acceptable. A negative Jacobian ratio causes SOLIDWORKS analysis to stop.

Call this method after ICWStudy::CreateMesh to calculate the worst or highest Jacobian ratio among the elements of this mesh.

See the SOLIDWORKS Simulation Help for more information about Jacobian ratios and meshes.
