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 of 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 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.

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

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

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

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