heat condution test fails

[Toby-Yang]

has anyone tested the 1d heat conduction problem? I found PeleC failed to get accurate temperature distributions

can you give us a little more specifics for this case? Specifically about the bcnormal function you are using to impose the isothermal wall. An earlier closed issue #263 may answer some of the issues you may be facing.

[Toby-Yang]

thanks for you answer. I test a new case using NoSlipWall, the temperature distributions is not agree with the results obtained with CHEMKIN package. So I think bcnormal function is not not relevant to this issue

[hsitaram]

How are you imposing the fixed temperature at the wall without bcnormal? are you using an EB?

[hsitaram]

Feels like an issue with transport coefficients. Can you share your case with us? What chemistry_model are you using?

Hi, two suggestions:

• can you run with pelec.do_hydro = 0 ?
• as a sanity check, can you print out the transport coefficients and make sure they match what you would expect for N2?

Thanks for your suggestions. I run with pelec.do_hydro =1, then it didn’t work . Finally I found it was caused by units
