Hi

I am not new to this forum. Though I haven't posted a lot, but I do learned a lot from the experts in this forum.

I encountered a problem.

I mapFields the latest result from a coarse mesh to a finer mesh.

The finer mesh passwd checkMesh. Though it failed when I chenMesh with -allTopology.

I can still have the result from coarse mesh mapped into the finer mesh.
In the paraview, I check the CH4, O2, CO, N2, CO2, CO, H2O are all mapped well.

However, when I tried to run reactingFoam with the finer mesh with mapped result as the initial. It failed.

Please give me some tips on solving this issue. Thank you.

It showed the following error when running reactingFoam

-->FOAM FATAL ERROR
Sum of mass fraction is zero for species 7 (O2 H2 H2O CH4 CO CO2 N2)
