Hi, Design modeler of Ansys is good. It has both options of extracting mid-surfaces manually and also automatically.

For any given analysis I see that most people end up choosing Hex mesh but why not second order Tet mesh ? I know some of the advantages of Hex over Second order Tet- 1. For a given model the hex elements would produce lesser number of elemnts than the tetrahedron elements. 2. Number of...

Cool....! those where very nice reponses. Thanks to all. I have few more in line.... Will post soon.

@ Corus... you are right. The node at which the SMX falls can be ignored if it can never occur in the real life situation. Now further on do you just see the range of the stress values to undertsand what the component is subjected to ? @rb1957... I really did not get you on code ? SMX is in...

Thanks for your reply... When we have the results the stress SMX is a numerical value and can be very high, but usually we come up with an absolute value which will be less than the SMX and say that is the maximum stress in the component. In gist, How do you say what is the maximum stress in the...

1. Do we have to look into Von mises stress always even if the material is not yielding ? What other parameters can be seen to justify the level of sress in the component ? 2. There are lot of opinion of limiting the stress value like we have to limit it to 2 element depth ot 3 element depth...
