Dear Kenza,
in line 118 of the fluidsystem header the H2OIdx is defined as 0, your
reading of the error message seems to be off by one and it's actually
looking for the binary coefficient for CH4 and O2. The combination isn't
matched because you order your component indices such that compIIdx <=
compJIdx but then test for compIIdx == 2 && compJIdx == 1.
Best regards,
Mathis

Dear Dumux Users,
I am writing to seek some help regarding the implementation of a
multicomponent fluid system in Dumux 3.4. Specifically, I am
simulating the injection of methane into a saturated porous medium,
where the aquifer contains dissolved gases such as O2, N2, and CO2 as
background gases. To accomplish this, I've been trying to implement an
h2on2o2co2ch4.hh fluid system and made all the necessary binary
coefficient files.
Although the code compiles without any errors, when I try to run the
test, I get the following error:
*/"what(): Dune::InvalidStateException
[binaryDiffusionCoefficient:/home/ggl/dumux3.4_KB/dumux/dumux/material/fluidsystems/h2on2o2co2ch4.hh:780]:
Binary diffusion coefficient of components 1 and 2 in phase 1 is
undefined!"
/*
There is an issue with the binary diffusion coefficient of components
1 (H2O) and 2 (CH4) in phase 1, which is the gas phase. However, the
gasDiffCoeff is well defined in the h2o_ch4.hh file!!
I would really appreciate any suggestions on how to address this
issue. All the files mentioned are attached.
Thank you in advance for your help and support.
Best regards, Kenza.
