Hello,

I was working on a topology optimization and I found


 *** ERROR # 557 ***
 DRESP1 2 is not referenced above the first SUBCASE.
 This type of response must be specified above the first 
 SUBCASE.
 This error occurs in DESSUB 2.

 

I read some topics but I didn't understand how to fix the problem.

Could you kindly help me understand?

Thanks in advance.


Alberto
