ERROR 312
Altair EmployeeHi
I am new to hypermesh and currently I'm working on topology optimization of control arm. But i'm getting the following error
A fatal error has occurred during computations:
*** ERROR # 312 ***
In static load case 1
the compliance is negative or large 9.504442E+10
Optimization/buckling analysis cannot be performed
due to possible rigid body mode
FEASIBLE DESIGN (ALL CONSTRAINTS SATISFIED).
I know it is due to rigid body mode and tried to change my constraints by varying dof's but still it doesn't run.
Can anyone explain me about this error?
