Hi,

I am writing script in hypermesh tcl command to create 3D meshing. for these i not understand  what the numbers mention here (8,0).

it is working in HM_13   and not in 14

*solidmap_prepare_usrdataptr 'SOURCE' 8 
*solid_prepare_entitylst elements 0 

 

Let me help to solve the issue.

 

Thanks,

Hi Jude,

For  *solidmap_prepare_usrdataptr 'SOURCE' option is a flag that indicate different option for solid mapping. Based on nodes or lines or surface or elements selected for solid mapping this value is calculated.

 

<?xml version="1.0" encoding="UTF-8"?>

 

For *solid_prepare_entitylst 0 has to be kept and it is reserved for future use.

Hi George,

Thanks for your reply,

 

I have one more clarification, i have to select the outer most element in a selected component how can we select it through TCL script.

I tried to get by element id but the number are not in order if i renumber also not work, how can i choose the outer element.

 

Thanks

You can't do that selection by elem ID.

Here's my method:

• Select 3D elems => Extract 2D faces (new component ^faces)
• Select 2D faces => elems => by adjacent => remove ^faces from selection => Got elems (see screenshot)

Based on my method, you can write a TCL script for that.

please try this:

 

*createmarkpanel comps 1 ' Select the component '
*findfaces comps 1;

*createmark elems 1 'by comp name' ^faces;
eval *createmark elems 2 [hm_getmark elems 1]
*appendmark elems 1 'by adjacent'
*markdifference elems 1 elems 2

set outer_elems [hm_getmark elems 1]
