Meshing is a very important parameter in finite element methods(FEM). It is very important to adjust the meshing according to the problem or physical situation in various FEA software. ANSYS® also offers very flexible meshing options to FEA analyses in ANSYS®. In Mechanical Base, we introduce the whole meshing options in ANSYS® Mechanical to obtain the most correct FEA solutions.
One of these options is Shape Checking options in ANSYS® Meshing. And we will show the what are the ‘Aggressive Mechanical’ option in ‘Shape Checking’ in ANSYS® Mechanical meshing options.
As you can see above the default Shape Checking option is Standard Mechanical. You can change the Shape Checking option of Meshing to Aggresive Mechanical as shown by the red box and red arrow above.
Aggressive Mechanical meshing is mush more restrictive meshing options than Standard Mechanical, which uses a much tighter Jacobian ratio at nodes. So, shape failure in the Aggresive Mechanical option is much more possible. Also, the Aggressive Mechanical option creates a much more dense mesh structure, and this takes much more computational time compared to Standard Mechanical.
By considering all of these facts about the Aggresive Mechanical option of Shape Checking, this meshing criterion much more suitable to Nonlinear Analyses or large deformation analyses.
Do not forget to leave your comments and questions below about the Aggresive Mechanical option of Shape Checking inANSYS® Mechanical.
