hole detection commands

Hi all,

I am trying to write a tcl script which can detect holes in the solid geometry.

For this purpose, I read HyperMesh reference manual, and saw the following commands:

*createmark elems 1 all

*findholesinit elems 1 2 45 0 0

*findholessolid 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0

*findholesend

I executed these commands on a tetra mesh (a solid block with some holes, meshed with tetra elements), and HyperMesh displayed following error:

'Need to first complete Hole Detection preparation'; this runs *findholesinit command '

These commands can be found in the EXAMPLE section of this page at HyperWorks' website:

http://www.altairhyperworks.com/hwhelp/Altair/hw12.0/help//hwdref/hwdref.htm?_findholesinit.htm

I have tested this method with various solid geometries and solid meshes, and always got the same error. Anyone having idea about this issue, kindly give some helpful comments.

Best regards,

Mubeen.

    Hi Mubeen,

     

    try the following:

     

    *createmark elems 1 displayed

    *findholesinit elems 1 3 30 0 0

    *findholessolid 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0

    *findholesend

     

    the example is still a copy/paste bug in the manual. It is the process for shell holes...

     

    Regards,

    Mario
