Hello, I am trying to compare a physical strain measurement on a sample taken with a strain gauge. This measurement gives an average strain over an area that the sensor is adhered to. In ansys mechanical, the simulation shows the local normal elastic strain in z dir. to vary significantly over the area footprint of where the sensor is. Is there a way to evaluate an average strain result in mechanical over a sub surface? Are any of the geometry editors able to partition a surface without splitting up the domain? See attached image, thanks!

Hi,
You can create a sub-surface in Discovery. If you click on the surface and then on the ‘Sketch’ tool, you can draw the outline that represents the strain gauge. Here’s an image:



Following this, in Mechanical, you can scope the strain result to that sub surface. You should be able to see the average of the strain results (along with the max and min) in the ‘Tabular Data’
