ANSYS Node Numbering

[Amroshafik]

Hi guys,

I have a problem to understand how ANSYS numbers the nodes. I have a code to determine the capacitance of a piezoelectric element. The writer used this code:

*get,npos,node,0,num,max

Then calculated the charge at this point

*get,Q,node,npos,rf,chrg

I don't understand why the maximum node number is selected to determine the capacitance here. I changed the code to the minimum node number, and the result is totally different. What is the relation between the node number and the value of the result it carries?

Thanks in advance

None. Maybe it is cycle between all the nodes to find max value?
