Rim well optimization problems

Recommended Posts

Hello,

 

when I do my optimization now, I get strange results.

Plies after Optimization.PNG

I really don't know where my fault is.

 

Another problem is, that I don't want to lose the no-material plies (see also:

http://forum.altairhyperworks.com/index.php?/topic/18205-interface-laminate-error-640/#comment-35811

Because, when I optimize now, I only can constrain the balance between 45°- and -45°-plies. But it is important, that the plies with no real material and the ones with CFK-Material have the same thickness, so that it doesn't change the midsurface. How can I realize that? Because in the picture above, I have hidden the no-material plies. the plies changed their midsurf and the diameter of my model went bigger, which is not allowed.

 

My other question is, how can I realize the plies to be continuously around the cylinder? I tried it with cyclic pattern grouping, but I am not sure if I used it right.

 

For further explanations please ask.

 

Thank you,

 

Konstantin
