Unsteady Conjugate heat transfer

oren · January 28, 2020, 03:56

Hey
is there an example for unsteady conjugate heat transfer in SU2? I'm trying to modify the test case with the flow around three heated cylinders to an unsteady problem and it doesn't works.

Try the develop branch, some bugs have recently been addressed an new testcases added:

Hi there,
I've modified those test cases myself some time ago and got some nice results (heatfluxes oscillating with the 'right' frequency, also the videos have not been looking too bad

). Though I'd have to search for them and see whether they required some modifications in the code.

I'll come back to this the next couple of days. Best, Ole

They do, but just a very minor one to set the same physical time step in all zones which has no proper solution in the (new) multizone framework so far.
So I just hacked it in some time ago and it still works fine.

I'll open up a work-in-progress pull request on github as soon as I have the results ready so that we can agree on a fix for that.
(Together with the adapted test case so that you can check yourself.)

Thanks for pointing us there. Ole
