Select Face(s) Select
Faces (Shell, Face), which will be
automatically meshed. Select Corner Vertices The
Mapped Mesh generating algorithm creates a square mesh by mapping a selected
shape into an imaginary square. It then maps the
generated mesh back to the original shape. Thus,
a group of four edges needs to be defined for mapping each edge of the
square. The edges of the face are manually grouped
into four edges by selecting four vertices of the edges composing the
boundary edges of the face. Mesh Size Element Size Specify
the element size. Specify
the number of divisions at the boundary edges of the shape for a meshing
operation.
<Advanced Option>
Sort Object Faces Specify
the order of Map Mesh generation. If Map Mesh is generated in multiple
Faces in a random order, it often fails due to unmatched number of seeding
between Faces. Therefore, defining the order will resolve it is recommended
to specify the order. CSys Choose the reference coordinate system between the Global Rectangular System and the Global Cylindrical System. Global Rectangular Sorts based on Global X, Y, and Z axis. Global Cylindrical Sorts based on Radius (R), Rotation (T), and Z-axis (Z).

Notes |
Mapped Mesh Algorithm First, appropriate seeding is assigned to the face for which mapped mesh will be generated, and the corner vertices are assigned. The corner vertices are indicated as A, B, C and D in Fig (i). The seeding between the corners A & B and between the corners A & D are assigned 4 and 12 respectively. The mapped mesh generating algorithm then maps the selected face into a square and generates a 2-D mesh reflecting the seeding as shown in Fig (ii). The mesh of the square domain is again mapped into the object domain as shown in Fig (iii). A main reason for failing to generate a mapped mesh is attributed to unmatched division numbers of elements for cross-faced edges. In the above example, the number of divisions for the edge A-B and edge C-D is 4. Similarly, the division number is identical for the edges A-D and B-C. Otherwise, the rectangular meshing is not feasible in the square domain.
In cases where the mesh fails to generate, refer to Remove Edge.

<Instruction>
1. Select face(s) to generate Mesh (if the shape is Shell, change Selection Filter to Shell) 2. Choose 4 corner vertices - (Normally, users are not required to select them. By not specifying them, the program will choose 4 corners which are close to perpendicular.) 3. Make sure Sizing Method is in Element Size (Refer to Size Control>On FaceĀ ). 4. Enter 30 in Mesh Size. 5.
Click 6. Click [OK] button.
Note 1. Map mesh is not suitable for all shapes. In those cases, user have to specify 4-corners or to adjust seedings on each edge properly. 2. To match nodal connectivity between faces, it is better to sew all Faces into a Shell. |
