Using experimental data (temperature) in Ansys to find conductivity

JannisSif · December 1, 2020, 06:05

Hi,

I am trying to simulate the following case:

A soil domain having two different layers of soil (thus 2 different thermal conductivities), which is being heated up on its top surface for a period of 3 years (transient simulation). However, the conductivity values are unknown.

I have experimental measurements of temperature in 4 locations in the soil (2 in each layer with different conductivity), which I want to use in order to find the two different conducutivities using the "optimization" component.

I think my case is quite similar to the one discussed in this forum https://forum.ansys.com/discussion/7...t-conductivity.

However, I do not understand how can I calculate in CFD-Post the temperature at a point in a specific timestep and then export it in order to use it in in the optimization procedure.

Thank you in advance!
Best regards,
Jannis

Boa tarde. Eu consigo estimar o fluxo de calor com as temperaturas experimentais usando outro pacote computacional. Sobre a condutividade, acredito que seja possivel.
