How to measure volume,area and mass using tcl

Altair Forum User

Hi,

How to measure volume,area and mass using tcl. In hypermesh by Tools --> mass calc..

I need to change the density to adjust the mass of a component. For that i need the volume of the component.

how to measure that using tcl...

if you need only volume:

*createmark comps 1 $compid

hm_volume comps 1

Thanks for the reply!!

How to get min/max values of nodes,elements,components??

For Max value i found 'hm_entitymaxsolverid comps'

For Min value ??

tinh

^.^ altair not provide command for min solverid ???

using hm_entitylist get list of i-IDs then convert to s-IDs

sort s-IDs list then you get minimum value

or : push panel 'renumber' => *createmark entity 1 all => hm_activateitem 'min/max' => hm_getmessage

Thanks for the Reply!!

But, i tried both i did't get the results..

set i 0

*createmark elems 1 all
set elemList [hm_getlist elems 1]
set elemMin [lindex $elemList $i]
puts -nonewline $fileId $elemMin

when i print the 'elemMin' nothing is there

i want to print the mininmum id's of nodes,elements,materials,systems and system collectors in a file...

And one more thing is i tried to deletemodel for importing new file...

I tried

*deletemodel

*deletemodel 1

*deletemodel

*answer yes

wen i run this it is asking the user to select yes or no...

Help me on this!!!

tinh

hi,

to get elemList selected on mark 1: hm_getmark elems 1 (not 'hm_getlist')

to ignore hm asking 'yes/no':

hm_answernext yes

*deletemodel

Thanks for the reply!!!

It worked..

How to measure mass using the tcl?

*createmark elements 1 displayed

for this mark i need to get the mass value....

tinh

hi,

there is no 'hm_mass elems 1 ' available to get mass

but make it your self

just take volume and multiply by density value in material card

Altair Forum User

Actually it is available.

*createmark elements 1 displayed

set mascalc [hm_getmass elems 1]

Mass = set mas [lindex $mascalc 0]

Volume = set vol [lindex $mascalc 1]

Area = set are [lindex $mascalc 2]
