Node (dot) in the middle of element (TCL?)

Daniil_22069

Hello everyone!

 

I have 3D tetra mesh and in the middle of any particular element of the mesh I have a dot.
It seems that this dot means nothing, couldn't find any information about it.

 

But for my project I need to get coordinates of those dots, without coordinates of the mesh.

As an example we can get .txt file with coordinates of elements of the mesh.
What I need to get is the same .txt file with coordinates but with coordinates of those dots only.

Should I use some TCL commands or is there any way to do that?

Very grateful for any help!

Here's a simple script to show you coordinates of centroid for each element:

 

 *createmarkpanel elems 1 'Select Elems' set my_elems [hm_getmark elems 1] puts '   Eid;     Center_X ;     Center_Y ;     Center_Z ;' foreach eid $my_elems { 	set cx [hm_getvalue element id=$eid dataname=centerx] 	set cy [hm_getvalue element id=$eid dataname=centery] 	set cz [hm_getvalue element id=$eid dataname=centerz] 	puts [format '%6d; %12.5E ; %12.5E ; %12.5E ;' $eid $cx $cy $cz] } *clearmark elems 1;
