Heat transfer post processing

Please login with a confirmed email address before reporting spam

Hello, I have the following problem:

after solving a comparably simple heat transfer problem I want to evaluate the temperature distribution in a domain in such a way that I want to know the temperature range (min and max temperature) of the domain after I remove 10% of the elements of the domain with the coolest temperature and 10% of the elements of the domain with the hottest temperature. Any way to do this?

Tobias,

here is a sketch of a possible procedure:

  • integration of 1 in the domain gives you the total volume
  • integration of T<T0 gives the volume that is cooler than T0
  • adjust T0 until you arrive at the 10 % fraction
  • this T0 is the minimum you are after and you can use it, e.g. in a filter for further evaluations

This may be automated in a model method. There may be other more elegant procedures using component couplings and equations from the mathematics interface.

Cheers Edgar
