Problem understanding sizing optimization

I'm very new to Hyperworks and have been working through tutorials and basic functions. During the skateboard tutorial it asks you to manually round up the upper bound of each autoply to the next 0.5, what is the reason for this when we also set the TMMANUF to 0.5 for all plies? or are these completely unrelated quantities?

Thanks!

    Hi SSnell,

     

    This is my understanding:

    Plies from the concept will be sliced as per the TMANUF. For instance If I have a ply from freesize with a upper bound thickness of 0.8 and my TMANUF is 0.5, only one ply will be generated with a thickness of 0.5 loosing 0.3mm thickness from the bundle.

     

    If I have a ply with a thickness of 1 mm and TAMNUF 0.5, I should get 2 plies with a thickness of each 0.5 mm.

    Thanks Prakash,

     

    That makes a lot of sense now, does this mean that the solver will struggle to observe the maximum thickness of the laminate that I define because we're manually adding thickness and only ever rounding up? because this is something I came across when comparing the element thicknesses of the output .fem file in hypermesh and hyperview.
