Obtain the area and perimeter of geometry in Hypermesh

Altair Forum User

Please, how can I obtain the area and perimeter of a 2D model in Hypermesh? Thank you.

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

Thank you. Where should I input these commands?

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.
