Week 5

Objective:

The objective is to check for the geometrical errors and mesh with the given element Quality criteria. Use tetra elements to model the component and there should not be any kinks and dips on the surface of the given component.

Procedure:

* Import the given CAD geometry into ANSA and after importing we need to perform some basic operations like

(a) Perform Topo for the given CAD geometry to stitch the cons perfectly.

(b) Do geometry check and fix if there are any errors present.

(c) Set the length of the Perimeter and macros to the given target or average length to check the quality of the geometry.

* After completing all the above mentioned steps now we need to input the the quality parameters and mesh parameters given for the geometry.

* Now i went for batch mesh opertion were ANSA deploys an automatic mesh based on the given quality and mesh parameters and one more advantage using batch mesh is here ANSA will defeature the geometry if its required automatically so that it will not affect the quality parameters given but some times we need to recheck if the defeaturing is done properly or not because it might affect the geometrical design changes which is not acceptable, In such cases we need to erase the mesh generated by batch mesh and redo the mesh using spot mesh.

* Now with the help of the shell mesh generated we need to generate a volume mesh or tetra mesh or unstuctured mesh.

* To perform the volume mesh first we need to define the volume and we need to remesh it again using tetra rapid or tetra fem we can use any of these algorithms to generate a volume mesh.

* In volume mesh we always look for only one quality parameter i.e, tetra collapse

* Conclusion:

Hence the volume mesh is performed for the given geometry using tetra mesh(unstuctured mesh) following the quality criteria given and the link of the result is attached above.
