    hi,

    I think u can use Tools>Mass Calc.

    There by selecting elements you will get area.

    perimeter

    geom>Length

    by selecting lines you will get.

    Thank you so much. 

     

    Please, how can I obtain the minimum area bounding box for a geometry in hypermesh?

    Hi,

    Try: 

    *createmark surfs 1 'Select geometry'

    puts [hm_getboundingbox surfs 1 0 0 0]

    Thank you.

     

    I am using hypermesh GUI. I do not know how to do tcl scripting. Please, what is the equivalent procedure for those codes in hypermesh GUI?

    Sorry Samuel,

    it should be:

    *createmarkpanel surfs 1 'Select geometry'

    puts [hm_getboundingbox surfs 1 0 0 0]

     

    you will be prompted to select your surfs, and it will output (at command window) bounding box

    I don't know other way to get it by hm GUI

    Please, find my attached geometry. 

    I want to implement topography optimization.

    Minimum area bounding box around my model = m

    perimeter of the model = p

    compliance = c

    f = m + p

    Objective = minimize f

    constraint: lower bound = 0.2*c, upper bound = 0.8*c

     

    How can I implement this? Note that perimeter and minimum area bounding box are not included among the design responses in hypermesh. 

     

    Thank you.

    Hi Samuel,

     

    isn't the unit of P and M are different?

     

    This makes F complicated parameter...?

     

    I need to check if there a way to provide geometric responses in OptiStruct

    Yes, the units are different. But that's what I need to achieve. 

     

    Thank you.
