DESCRIPTION AND PROCEDURE:
1. OPEN ANSA SOFTWARE. GO TO FILE TAB AND OPEN THE REAR MIRROR.
2. AFTER LOADING THE MODEL CHECK IF THEIR IS ANY SINGLE CONE IS PRESENT OR NOT. IF THEIR ARE SINGLE CONES THEN GO TO TOOL BAR FACE AND SELECT TOPO COMMAND AND CONNECT ALL THE SINGLE CONES.
3. AFTER THAT CHECK THE GEOMETERY. if you found everything ok then move to meshing.
4. GO TO QUALITY PARAMETERS AND SPECIFY THE QUALITY CRITERIA AS ASKED IN QUESTION.

5. THEN SPECIFY THEMESH SIZE AS 1MM .
6. GO TO MESHING TOOL BAR AND USE THE SPOT MESH FOR THE CRITICAL AREA AS ORTHO TRIA ELEMENT.
7. AFTER SPECIFYING ROUND AREAS AS ORTHO ELEMENT THEN GO FOR STRIAGHT FACES WITH SIMPLE TRIA MESH.
8. AFTER COMPLETING THE 2 D MESH.
9. GO TO VOLUME MESH TO SPECIFY THE VOULME TO THE MESH WHICH ARE WE GENERATED EARILIER.
10. TO SPECIFY VOULME GO TO VOLUME COMMAND IN TOOL BAR AND CREATE THE VOULME
11. TO CHECK WHEATHER THE VOULME IS GENERATED OR NOT GO TO LIST COMMAND AND CHECK.
12. TO CREATE THE TETRA MESH GO TO UNSTRUCTRED MESH.
13. SELECT THE TETRA FEM AND SELECT THE MODEL AND PRESS OK.
14. AFTER CREATING TETRA MESH GO TO SOLID MESH QUAILTY CRITERIA AND CHECK THE TET COLLAPSE AS ASKED IN THE QUESTION

15. AFTER CHECKING THE TET COLLAPSE SEE WHEATHER THE ELEMENT IS FAILING ANY WHERE.
16. IF ELEMENT ARE FAILING THEN RIGHT CLICK ON QUALITY CRITERIA AND SHOW ONLY.
17. GO TO IMPROVE AND SELECT THE FIX QUALITY AND VISILE ELEMENT. THAT WILL IMPROVE THE QUALITY.
RESULT:
