Hi Francesco,


  What version are you using? In 19.1, the manual says:




  • Global von-Mises Stress Constraint: This option is only available when there is at least one upstream Static Structural system. You use this property to make sure that the optimized geometry or structure always supports a specified maximum stress. When selected, the Maximum property also displays. Enter a stress value in the Maximum property as a Constant or using Tabular Data entries.




  • Local von-Mises Stress Constraint: This option is only available when there is at least one upstream Static Structural system. You use this property to make sure that the optimized geometry or structure always support a specified maximum stress using the Maximum property that also displays when you select the Local von-Mises Stress option. You specify the stress value of the Maximum property as either a Constant (default) or using Tabular Data entries (via fly-out menu). The application supports multiple Local von-Mises Stress constraints.




So, if you define local von-mises it should only work in the optimization region and shouldn't affect the whole part? Isn't this what you are seeing?
