Explicit Shape Checking In ANSYS® Mechanical(Illustrated Expression)

Explicit dynamics are frequently used systems in Finite Element Methods(FEA). So these kinds of systems require very specific meshing types and features. These meshing features and types are provided by ANSYS® Meshing. And it is very important to adjust the meshing according to Explicit Dynamics analyses in ANSYS® Meshing. So one of the options to adjust the mesh structure according to the explicit systems in ANSYS® Meshing is setting the Explicit Shape Checking. In this article we will show you;

  • What is Explicit Shape Checking in ANSYS® Meshing,
  • How the Explicit Shape Checking is adjusted in ANSYS® Mechanical,
  • Where to use Explicit Shape Checking in ANSYS® Mechanical.

Explicit Shape Checking Criterion In ANSYS® Meshing

Explicit Shape Checking in ANSYS® Mechanical.

The default Shape Checking criterion in ANSYS® Mechanical is the Standard Mechanical option. You can adjust the Shape Checking criterion as Explicit as shown by the red arrow above.

The Explicit Shapa Checking is using a shape checking criterion based on Jacobian ratio and element volume which is special to Explicit analyses in ANSYS® Mechanical. As its name implies that it is recommended to use in Explicit Dynamics analyses and other explicit analyses in ANSYS® Mechanical.

Select the Explicit for Physics Preference in ANSYS® Mechanical.

It is also strongly recommended to select the Physics Reference to ‘Explicit’ as shown by the red arrow above in ANSYS® Meshing.
