CFD Shape Checking In ANSYS Mechanical(Illustrated Expression)
Fluids are generally used finite element analysis(FEA) pyhsical situations called as CFD. So it is very important to adjust the meshing according to the fluids or CFD. ANSYS provides very useful meshing capabilites or meshing tools for CFD problems. One of these meshing options for CFD problems in ANSYS is Shape Checking criterion. In this article of Mechanical Base we will explain;
- What is CFD Shape Checking and where to use it,
- How to adjust the Shape Checking to CFD mode in ANSYS Meshing,
CFD Shape Checking Option In ANSYS Meshing
The default option for Shape Checking criterion ANSYS Mechanical is Standard Mechanical. If you have a physical problems with fluids, you can adjust the Shape Checking criterion to CFD as shown by red arrow above.
CFD Shape Checking criterion uses element volume method for non-assembly meshing algoritms. But if it is a assembly meshing algoritm, orthogonal quality shape checking criterion is used for CFD Shape Checking option.
It is strongly recommended to use the CFD Shape checking criterion by selecting the Physics Preference as ‘CFD’ also, as shown by red arrow above in ANSYS Meshing.
