Question TM, setting temperatures in objects

1

Dear all,

I am currently trying to model a pile with OGS and I want to reproduce heating and cooling cycles of the pile. Is there anyway I could group the nodes inside the pile and set the temperature in each of them and change them during the simulation? I am asking because in all the examples I have found so far, there is an initial temperature and then changes in temperatures are assigned in the boundary conditions.

Thanks for your help,
Maria

Hi Maria,

yes, temperature has to be set via a Dirichlet BC.

If you have a simple setup, combining a Dirichlet BC with a curve scaled parameter for time dependence is an option.
If your setup is more complex, a Python BC might be more convenient.

In any case you’ll have to create a boundary condition mesh for the grouped nodes.

Best regards,
Christoph
