    Hello,

     

    I do have this problem now:

     

    After optimization almost every ply has a very small angle of orientation. 

    Any idea why this is the case?

    In the design variables I have assigned a minimum of -180 degrees and maximum of 180 degrees

     

    Could it have something to do with radians? since in other test optimizations it worked with these settings.

     

    Best,

    As suggested, it is always better to start with thickness optimization with a varied orientation. Please see the image for more information.

     

    The predicted orientations may not be practical and any degree in the angle may lead to failure.
