solid model volume numbering 2

[lwf]

I created two volumes by using the V commend. then I'd like to substrate one from the other by using the VSBV command. This needs the volume numbers. Please advise how to number the volumes, what is the command? Thank you.

The user has no way of modifying volume numbers. In your situation it might be advisable to select volumes by location, assign them to a component, then reference component names instead of volume numbers in your VSBV operation.

The above poster is right. Setting components is the easiest way to name a volume. If you are having trouble actually finding the volume to name, you have a few options. First of all, in the GUI you can turn on volume numbering in the PlotCtrls menu. You can use the VLIST command to list all the currently selected volumes. The numbering will not be natural (i.e. they will not got 1,2,3... in order of creation), so this can be handy to narrow down what volume numbers actually exist. You can also use the VPLOT command to plot individual volumes (e.g. VPLOT,5 to plot volume 5) if the volume you are looking for has an obviously distinct shape.

In a APDL model what you can use:
Create each volume with before and after:

vsel,none
v,.......
vvv1=vlnext(0)

vsel,none
v,.......
vvv2=vlnext(0)

then your VSBV command:

VSBV,vvv1,vvv2,....

And you can enable volume numbering display in the plot controls menu, then plot the volumes and find out which volume is what.
