hi ,
am not able to generate vol mesh using tetrahedral cells.getting an error, plz let me know where i went wrong

it seems you have skewness problem.
If you get a 3d mesh check volume mesh quality and check where is worst element.
If you don't get 3d Mesh, do the same but in 2d.

hi max,
i got a crude mesh at-least as a preliminary one.i wanted to know how much of quality of cells is satisfactory as a thumb rule .i got a quality of 0.85 for the worst element.
also before going for refining the mesh by moving nodes,what other steps can be taken to improve the mesh(tetra).

0.85 for tetra is good.
If it is not already done, try to mesh it with tetra-hexcore (it filled the core of your domain with hexa)--> very powerful
