boundary conditions help
(OP)
Hallo, I must model a structure where I have a Silicon die with some thin film material on top. The film is deposited at high temperature, then cooled down. during cooling stresses and strains are developed inside and partially released by system bending (see attachment).
My question is: which kind of boundary conditions should I use for the model ? I cannot just fix all the die bottom (this would not allow it to bend). So I thought I could just fix a single Point (total fix: 3Dof Rotation and 3 dof traslation).
Do you think that is correct ? Else, do you have any other Suggestion ? Thanks

(1) could you please be more specific or make a sketch regarding your answer ?
(2) also, assuming that there is no simmetry (in this case there is, but a following case could not have), what is the general way ? If I model the entire block, is it sufficient for me to fix completely only one point ?
