Static Displacement constraint not working
Altair Employee Hello Guys, I am trying to optimise Carbon fibre's square plate with Opti struct as a solver. For optimisation, my objective is to minimise the mass and constraint on the particular node's displacement( which is 25 mm ) in the direction of application of force. When I am running optimisation I got a message 'OPTIMIZATION HAS CONVERGED.
FEASIBLE DESIGN (ALL CONSTRAINTS SATISFIED).' But the displacement of constraint node is 40.32mm. I am not understanding why static displacement constraint is not working in my case. Could you guys please help me?
Thanks for your help.

Altair EmployeeHi Sanket,
Looks like the model is not properly constrained. Can you share the complete .out file?
As per you said I sent you .out file.
Altair EmployeeSanket,
Can you share the .fem file, I dont see anything unusual in .out file.

Hello Prakash,
I sent you .fem and .hm file
Thanks
Altair EmployeeSanket,
Your optimization results are correct, maybe you should change the setup of optimization.
You have constrained the displacement of node 491 to 25 and this is respected.

Hello Prakash,
Thank You so much for your help. Now I constrained the correct node and got correct results. Thanks
