Reply To: equality constraint in optimization

[Md_Salem]

Hello,

I solved the 1st problem. The main cause of it was that I duplicated the identification of (H9 and V7) once as (@Sh,@Sv) and the other as targets for the two equality relationships, and this may have led to confusion of the solver. So, when I deteleted 1st identification (@Sh,@Sv) and just kept the 2nd identification as targets for the two equality relationships, it worked properly.

Unfortunately, I couldn't solve the second problem, despite doing as you told me, as shown in the next picture.

Further, I made sure that the default material update is "yes," as shown in the next picture.

 

What would you think is a probable cause for such a problem?

regards
