Ansys Workbench APDL select volume

Ansys Workbench APDL select volume

(OP)
Hi,
I try to select volumes via APDL in ANSYS Workbench but command VSEL return empty selection. So I check the model by /STAT,GLOBAL and there are no volumes (keypoints, lines, areas either).

I know the trick that I can access volume via Named Selections using CMSEL command but is there any way to access the volume without CMSEL command?

Best regards
Jrz

RE: Ansys Workbench APDL select volume

May I inquire why CMSEL is not sufficient? What are you trying to achieve with the code snippet?

RE: Ansys Workbench APDL select volume

In /prep7 type:

allsel

and then:

vlist

If the list comes back as empty then there are no volumes in your model, so regardless of whatever you try and do (CMSEL or otherwise) you are asking ANSYS to list or show information on an entity which doesn't exist. It sounds like there's nothing at all in your model actually, but try:

allsel
gplot

and see what ANSYS shows.

RE: Ansys Workbench APDL select volume

Hi,

L_K: I try to select solid elements only that are attached to the volume(s) then do some operations on them. When I use CMSEL, surface elements are select too.

Drej: When I'll be back at work I'll try your advice. But what I remember ANSYS Workbench tells me that there are elements and nodes only, no geometry, that's odd for me.

RE: Ansys Workbench APDL select volume

Hi,

If your solid elements are SOLID186 (default in Workbench Mechanical), this code should select only the solid elements.

CMSEL,s,box
esel,r,ename,,186

, where box is named selection of the body in question.

Maybe there is a more sophisticated way but this should work.




RE: Ansys Workbench APDL select volume

Hi Jrz,

Ansys workbench does not transfer geometry to APDL so commands such as VSEL wouldn't work. A named selection on volume in workbench selects the elements. All others entities will select nodes associated with the geometry for use in APDL.


Best regards,
Jason

Hi,

Drej: As sk_cheah said not possible.

L_K: Thanks for

CODE --> APDL

ESEL,R,ENAME,,186 

Why I missed this command is mystery for me.

At this point I stay in combination of the CMSEL command or

CODE --> APDL

ESEL,S,ENAME,,186
ESEL,A,ENAME,,185 


Thanks all of you.
