Hello,
I am trying to do a topology optimization on an automotive part for fatigue damage. The process I am following is
- Define the fatigue damage as response using the fatigue loadstep created.
- Define design constraint as damagevariable<1.
- Create a response for volume fraction.
- Define objective function as min volume fraction.
- Create a topology optimization desvar with damage less than 1 in parameter section.
It however gives an error :
Fatigue responses are applied to property 688188 which belongs to a
topology or free-size domain. For fatigue-constrained topology or
free-size optimization, please use the FATIGUE option on the design
variable definition card.
If someone is aware of the problem please help me.
