How to find area of a single mesh element
I have a temperature field along a x-y plane but I wish to multiply the corresponding temperature of a node with the area that it occupies.
For example, in my derived plane there exists many different sized elements of different shapes (because I am using a polyhedral mesh and cutting through a section). Is there a way to find what each corresponding nodes' areas are and then multiply by it's own temperature?
This would then be calculating a quantity with units of degree multiplied by area.
Thanks so much for your help!
field function area is available on boundaries but not derived parts like a section plane. so you could place an interface between 2 regions at that location and you will be fine - create a field function $Temperature * mag($$Area) to display or report on.
an approximation might be possible using volume rather than area.
