Extrusion in free shape optimization

I want to use 'Extrusion Constraint' in free shape optimization to simulate the manufacturing condition.

The model here is a cylinder with a hole to be optimized,see figure 1.

After optimization has been converged, the results show that 'Extrusion Constraint' doesn't work.Please see figure 3.

Hope the optimization experts could help me realize the extrusion in free shape opt. Thanks very very much!

Hi,

Sorry for a late reply. I lost this in stream of questions.

I dont see any extrusion parameters in your model. Can you update the same?

Thanks very much for your reply. I only select extrusion direction parameter in free shape panel.The direction is along the hole {X:1 Y:0 Z:0},see figure attached.ex

Results show that extrusion direction doesn't work, which puzzles me. Hope you can help.

I update the model again.

Hi,

In the last file I did not see any extrusio direction. I will update and will check at my end.

Hi,

Please see the image below with draw direction along the length of hole and shape type is set to grow.

Thanks! Could you please share the .fem file with me?

I export the .fem file and check the Dshape card, and find there has EXTR option.Actually, I strongly need extrusion instead of draw.

Well you can have only EXTR with GROW option active.
