Curved skewness, which is defined as the elementwise product of skewness and reldetjacmin, which is a measure of the deformation when generating the higher-order element (see Geometric Variables and Mesh Variables). When curved skewness is evaluated in mesh statistics, the deformation always use the second-order Lagrange geometry shape function. If you want to evaluate curved skewness for some other geometry shape function, you can do so by evaluating the built-in variable qualcurvedskewness on a mesh dataset with the desired setting or a solution dataset. If you plot the mesh from the solution dataset, you will measure the same deformation as in your solution. If you use a mesh dataset, you need to set the desired geometry shape function explicitly. The default geometry shape function for the mesh dataset is linear, which makes skewness and curved skewness equivalent. You can use a plot of the curved skewness to find badly shaped mesh elements.

The qualcurvedskewness measure is equivalent to qualskewness for face elements not adjacent to domain elements in 3D.

Using qual without a frame suffix refers to the material frame if several frames are used.

In general, if a mesh with a low mesh quality has been generated, a Warning node appears, indicating where the bad elements are located in the geometry. To locate the exact placement of the bad elements, use a Mesh plot node set to show elements of the right dimension and using an element filter like qualskewness<0.01.

By default, this plot shows the mesh element quality. You can choose the mesh quality measure to display from the Quality measure list. In the Settings window for Mesh, select Size instead of Quality from the Element color list to plot the mesh element size instead.

Add a 2D or 3D Plot Group using the Mesh dataset as the group’s dataset, and then add a Surface or Volume plot. For example, in a 2D Plot Group>Surface node (), from the predefined quantities (under Mesh), select qualskewness - Element quality (the default mesh quality measure), h - Element size, or one of the other available mesh element quality quantities for another quality measure. Then click the Plot button ().
