How to define evaluation faces while keeping the volume body?

  I want to study the acoustic behavior of pipes and pumps. Furthermore I am interested at the impact of the mesh resolution and usage of different element types for the acoustic behavior.
  Therefore I need to evaluate the acoustic pressure and velocity at certain locations of my geometry.

  ,nYou could create named selection through a worksheet, which allows you to select nodes, elements specific location/range of distance. After doing this, you could add a result probe and scope it to this named selection. You could follow this video
  (just use criteria as 'distance in z' instead of node id).nnLet me know if this answers your question.nRegards,nIshan n

  nsorry for my late response. I got a few questions regarding the workflow you mentioned. nIf I am using the auto mesher, I do not know at which location the nodes have been placed. It occurs that I am trying to insert an element face or pick a node at a certain distance but there are not any. I moved on to prescribe a distance interval in which the element face or node should be, but then multiple nodes are selected and not only one. Currently I am trying to use filters with the prescribed distance interval and I am wondering if I could pick certain nodes of this filter.nThanks for your help,nJan n

  ,nIf you want to pick out only certain nodes, I think the best way would be do do it manually. You could just click 'node select', then click on the mesh nodes you want to add (these would get highlighted) and then right click>named selection. This would create a nodal named selection for certain nodes only.nnRegards,nIshann
