Hello,

I am using reactingFoam to run my simulation. I turned off the chemical reactions by putting "chemistry off" on "chemistryProperties" file and I am getting the following errors:

I believe all the errors are related to the first notice and from what I have understood, it is a problem of Ostream. But I am using the original solver reactingFoam, which works fine for the tutorial counterFlowFlame2D and so i dont understand this error for my simulation


This is the .log file:

It stops here.


Any help is much appreciated!

Thank you

Ok i think i found what is wrong.

Some of my BC's have all the mass fractions equal to zero, since they are solid walls. But how should I define the mass fractions in another way on these solid walls? :/

Hi,

just use zeroGradient, this means no diffusion of species towards the wall.

Hi, thanks for your reply Tom! I will try that
