The refinement area is circular with its centre in a specified point. The finite element size outside the circle is the standard FE size for 2D elements adjusted in FE mesh setup dialogue. The element size in the centre of the circle is the given refined value. The size of elements in between varies linearly from the two limits.
|
Name |
Identifies the refinement. |
|
Radius |
Defines the radius of circular area where the mesh will be refined. |
|
Ratio |
Defines the ratio between the average element edge size in the centre of refinement area and the average preset element size. |
|
dx, dy, dz |
Defines possible shift of the centre of refinement area from the specified point. Thus the refinement area may be placed anywhere in the structure. |
|
Type of point mesh refinement |
Linear increment = elements at the end are larger, elements in the middle are smaller Equidistant - only 1D element = the elements are uniformly refined |
Call function Node mesh refinement using tree menu function Calculation, mesh > Local mesh refinement > Node mesh refinement.
Adjust the parameters (see above).
Confirm with [OK].
Select nodes where the refinement should be used.
Close the function.
If you want to refine also mesh of 1D members , you must allow this in Mesh setup - see the Parameters_of_FE_mesh chapter.
