OF1.7: coalChemistryFoam/simplifiedSiwek error

Hi,
As discussed in post "Patches for OpenFOAM 1.7 on MacOS X", the case of coalChemistryFoam/simplifiedSiwek error on Mac and Linux, log reads,
=======================================

Code:

Courant Number mean: 0.1533929535 max: 0.6093346791

deltaT = 0.0005

Time = 0.252



Cloud: coalCloud1

Total number of parcels added = 27

Total mass introduced = 0.0001

Current number of parcels = 27

Current mass in system = 7.634816181e-05

Mass transfer phase change = 2.487806921e-06

Mass transfer devolatilisation = 1.096268892e-05

Mass transfer surface reaction = 1.020134234e-05

check it.

The same errors occurs in Linux and Mac ports.
nobody response it?

Leo

Thanks for reporting - we have updated the tutorial in 1.7.x

Heloo Andrew and folks,

This in relation to the error that is reported by Leo. I assume that Andrew has updated the tutorial and there is no error.

I am interested to know what is the remedy to be taken to avoid this error? Could you please share what are the steps/modifications that were done to avoid the error?

Description of my error: I get similar kind of error in OF1.6 version for the modified coalChemistryFoam. Instead of char burning, I have implemented char-gasification chemistry (hetrogeneous chemistry).

Thanks,
Nir

Hi，Andrew
you said the tutorial have been updated in 1.7.x,I use OF1.7.1,it's still the same problem,I hope you can help me ,and what is updated in new version?
thank u!

Hi,Nir
do you use coalChemistryFoam?my case has two inlets/one outlet,I use the updated OF,and for my case it shows the same "out of temperature range"problem,do you know how to solve it?
Best regards
ying
