Parallel Deviation Mesh Metric In ANSYS® Meshing(Illustrated Expression)

1 min reading time..

In the mesh metrics option of ANSYS® Meshing, there are a bunch of parameters that you can select around to see the mesh structure’s situation. This is a very useful tool and all of these parameters are explained in Mechanical Base. One of these mesh metric parameters is ‘Parallel Deviation’. In this article we will explain:

  • What is ‘Parallel Deviation’ in ANSYS® Mesh Metrics?
  • How the ‘Parallel Deviation’ is adjusted?

What Is Parallel Deviation Mesh Metric In ANSYS® Meshing

Select the ‘Parallel Deviation’ mesh metric in ANSYS® Meshing.

To adjust the mesh metric to ‘Parallel Deviation’ in ANSYS®, click on the ‘Mesh’ tab then select the ‘Parallel Deviation’ as shown in the red box above from the pop-up menu as shown by the green arrow.

After the selection of ‘Parallel Deviation’ for ‘Mesh Metric’, you can see the minimum, maximum, average, and standard deviation values of parallel deviation of mesh elements. Also, you can see the dispersion of parallel deviation values around the number of mesh elements from the above chart in ANSYS® Meshing.

If we explain the parallel deviation in mesh elements, this is the angle between the edges of quadrilateral mesh elements. If the angle is increased, the parallel deviation of the mesh element increases.

Parallel deviation example for quadrilateral elements in ANSYS® Meshing.

As you see above, if the parallel deviation is 0, the quadrilateral mesh element will be a rectangle. When the angles between the edges of quadrilateral elements are increased, the parallel deviation value is also increased.

Conclusion

This can be the most basic expression of ‘Parallel Deviation’ in ANSYS® Mesh Metrics. If you have any questions or comments about ‘Parallel deviation in ANSYS® Mesh Metrics’, leave them below!
