Hello Suzon,
I'm not sure if this is really where you are working, but assuming:
- the error you are working on is coming from the "evaluateInterfaceFluxes"
function,
- in porousmediumsubproblem.hh header file,
- and you have added a call to evaluate the face-wise flux at somepoint that
looks like this:
>
NumEqVector flux =
couplingManager().couplingData().massCouplingCondition(element, fvGeometry,
elemVolVars, scvf)
* scvf.area() *
elemVolVars[scvf.insideScvIdx()].extrusionFactor() * FluidSystem::molarMass(1)
* -1.0 * 86400.0;
> (taken from the exercise solution)
Then there will be a compatibility problem between the call to the
"massCouplingCondition(...)" function, and the type NumEqVector.
NumEqVector will have three entries (FieldVector<[...],3>, including the added
temperature), and the returned vector from the massCouplingCondition(...)
function will only have two entries (FieldVector<[...],2>, only evaluating the
mass fluxes).
To fix this, you can use the correct type (for this I would recommend to simply
use the auto type).
If this is not where your error is coming from, it would be very helpful if you
could send us a bit more output from the compiler error. This is just a best
guess based on the line number and error you have mentioned.
Best,
Ned

Subject: Re: [DuMux] Non isothermal coupled exercise
Hi Christoph,
I was able to use non isothermal condition with another example using TwoPNCNI
model so I guess that the problem comes from the coupling part.
I assume that indeed the temperature should be taken into at the coupling
interface but I am not sure how to do that.
Should I modify something in the couplingManager ?
Thanks for your help,

Hi Suzon,
I did not look into the code, so I might guess wrong.
I suspect that by adding temperature, you got a third primary variable. The
error points out that you are using a vector with two entries (representing two
primary variables) at a place where you should use a vector with three entries
(for all three primary vars).
I hope this helps you figuring out what went wrong.
Bye
Christoph

Hi all,
I am now working from the coupled exercise
(exercises/exercise-coupling-ff-pm/models) with a 2pnc model. I wanted to make
it non-isothermal so I change TwoPNC by TwoPNCNI and NavierStockesNC by
NavierStockesNCNI in the properties file but I get the following error :
error: conversion from ‘FieldVector<[...],2>’ to non-scalar type
‘FieldVector<[...],3>’ requested
263 | elemVolVars[scvf.insideScvIdx()].extrusionFactor() *
FluidSystem::molarMass(1) * -1.0 * 86400.0;
I don't understand what does it mean. Does anybody know how to fix this problem
?
Thank you
Suzon Jammes
