OpenFOAM XiFoam Tutorial FPE Error

Bish · August 30, 2017, 14:20

Hi All,

This is my first post!
I have been using OpenFOAM for just over a year now for my PhD in combustion modelling.

I am trying to complete the following tutorial: http://www.tfd.chalmers.se/~hani/kur...sariReport.pdf

This is adding a new algebraic model to compute the turbulent flame velocity.
As this was written for a much older version of OpenFOAM, certain header files etc have changed.

I receive a FPE error which I have tracked down to alphaEff and alpha being the same value which causes tau prime to be zero and hence eventually dividing by zero.

Has anyone tried this tutorial? and come across this error?
Or is this due to the differences in OpenFOAM versions in which I need to correct some dictionaries? I know the major change from from v2.1 to v2.2 in which the hEqn and huEqn changed to EaEqn and EauEqn which could have some knock on effect.

Any help/ideas would be much appreciated.

Thanks,
Bish

Hi Bish!

I am also facing the same problem. Did you find any solution for the problem?
