Week 4

AIM

To check for the geometrical errors and to mesh with the given element quality criteria and after meshing the component the thickness has to be assigned for the given component.

PROCEDURE

• First the given component is to be done TOPO. Here the given component is BOTTLE CAP MODEL.
• Then is length between the two nodes must be adjusted according to our needs. For that in MESH mode, under perimeter LENGTH is selected and under that for both PERIMETER and MACRO value is given as 1 to get fine edges over the model.
• Then the model is check for geometry in CHECK GEOMETRY. Then execution is done till zero errors.
• Then thickness is measured which helps to create the midsurface.
• The Quality criteria is assigned as per the given data and TARGET LENGTH, Min. Length and Max Length is also assigned.
• For midsurafce creation there ae many methods like AUTOMID and MANUAL MID GENERATION or by OFFSETTING the face or by creating the middle for curve and create a new face between them.
• Here for this I have generated the midsurface by manual method.
• And for some areas have offseted the faces.
• After creating the entire midsurface it should be done TOPO.
• After topo is done, this midsurface alone should be given a seperate Property using SET PID. And create a seperate property and assign a different color for this.
• And for the midsurface also length is assigned as 1.
• And for meshing also there are many methods such as BEST, BATCH etc, so here i have chosen the BEST mesh option for meshing.
• And RECONSTRUCT , SMOOTH for better mesh flow for the selected area.
• And to avoid tria mesh elements i have used SPLIT, SWAP options in mesh mode.
• And while setting PID thickness is assigned based on the parent surface.
• and after completing the meshing for the entire component under PRESENTATION PARAMETERS, shell as solid option is selected.
• And now the midsurface is turned as solid with the assumed thickness.
• Now the complete MESH is done.

LEARNING OUTCOMES

Have learned the meshing process for complicated surfaces and taking midsurface for fillet area. and learned the technnique for best mesh flow.

CONCLUSION

Hereby I conclude that the geometrical errors is corrected and mesh is done for the given element with the assigned Quality criteria and thickness is assigned.
