How to rectify the ERROR # 312 In static load case 1 the compliance is negative or large 1.07647e+008. Optimization/buckling analysis cannot be performed. due to possible rigid body mode. INFEASIBLE DESIGN (AT LEAST ONE CONSTRAINT VIOLATED).
hello Every one ,
i am doing optimization in topology ,i got some error in below how to rectify that one , and also i check mesh connectivity and rigid link and constraint all , but i have same error will be repeated how to rectify and give me solution .
here i attached .hm file

hello @Prakash Pagadala
i check constraints correctly assigned , please check it .hm file here i attached , give me solution
Sorry for the multiple post in same question wrongly upload its again and again
Altair EmployeeYukesh,
Can you constraints in all directions and check?
ok, its solving but as per bc why its not solving and is there any solution please give me to solve
Altair Employee
The model is free in the direction of loading which means infinite compliance. Constraint in Z direction (which is loading direction in your case) and check the results.
Hi @yukesh.aero
Check the loads and boundary conditions.
If the constraints are applied on free nodes/temp nodes, solver exits with same error.
Re-think about the Dofs constrained in your model. check the run with all Dofs constrained.
