Defining Element Size Of A Body In ANSYS® Mechanical(Illustrated Expression)

In general, if you decrease the size of the mesh elements in ANSYS® Meshing or general meshing in Finite Element Methods, the accuracy of analyses will increase. But there is a limit to that accuracy after a decrement of the mesh size. You can find out this limit by defining your element size in ANSYS®. So you can learn how to define our element size in ANSYS® Meshing here.

How To Adjust Elements Size Of Mesh Structure In ANSYS®?

You can actually define the mesh size of bodies or faces in an assembly separately in ANSYS®. It gives a great advantage to adjust your mesh density at required parts and unrequired parts.

Click on the ‘Sizing’ option in ANSYS® Meshing.

To adjust the size of mesh structure in a feature in ANSYS®, right-click on ‘Mesh’ as shown by the red arrow above then hover your mouse on the ‘Insert’ tab, and select the ‘Sizing’ option as in the red box.

Select your geometry to adjust element size in ANSYS®.

After selecting the ‘Sizing’ option, select your geometry such as a body or face from the red box region, then click on the ‘Geometry’ tab once, then click ‘Apply’ to select body.

Define your mesh size for your selected geometry in ANSYS®.

You can enter the size of a mesh element that will be created on your selected features in ANSYS® as shown by the blue arrow. Select one of the options in the blue box as ‘Soft’ or ‘Hard’ which is a transition option for your mesh structure. If you select hard, the transition between dimensions of your mesh structures will be sudden. Soft is a moderate selection to obtain less accurate mesh structures.

Click on ‘Update’.

If you finish the sizing of your mesh, right-click on ‘Mesh’ then click on ‘Update’ as shown by the blue arrow above in ANSYS®.
