how to find second order derivative of temperature
Title
Question
Good evening sir,
I am doing a natural convection problem in which i want second \r\nderivative of a scalar i.e Temperature T
How can i implement it in openFoam?
Double derivative of Temperature with repsect to x or y ?

Is it possible to calculate in paraview ?

Answers:

Hello vnarayana.wgl,

1) If you need to calculate the second order derivative of Temperature, you may implement groovyBCboundary condition on the respective patch.
2) The derivative will depend on the direction of heat transfer.
3) Paraview is a post-processing tool. You may analyse the results(variation of temperature) using it. You cannot calculate your results using Paraview.
