Hi,

 

I am currently working on my final year project. I am getting this Error :

 

 

I currently need urgent help on this topology optimization. I keep getting:

*** ERROR # 2148 ***
 Invalid design problem.
 All the sensitivities of response 2 (objective) are zero.

 

 

I am unsure how to fix this and have been trying for hours going through the forum and trying different things. I have attached the file to this message.

 

Also:

 

1)My beam in real life is welded on each end,so simply supported. Have I used the correct constraints?

2) There is a 150N distributed load on each circle. Could you confirm that turning the Load into a pressure and dividing by the number of elements on the circular face is the correct way of doing this?

 

Could you please help me with this? I need this urgently and would really appreciate a quick response.

 

 Thank you,
