mapFields failed
 
Hi All,

in my simulations, I always use mapFields to map the results from the coarse meshes to the fine meshes. This is succesful from my 5 million meshes to 7 million meshes. Now I would like to map the results from 7 million mesh to 10 million mesh, I got the following error:

I do not know why, the only thing I did is to refine the mesh and copy the results from the coarse mesh to fine one. The geometry, solver and other settings are totally the same. in order to rule out this error, I also regenerate the mesh (of coarse, around 10millim). From the above information, it seems that the solver failed to read in the reaction information and the thermodynamics model. Because when I used the same procedure (mapFields ../case -consistent), I got the successful mapping. But for this case, I am completely confused.

Could you please give me some hints about this problem? I really appreciate it if you can help me.

best, h

The reason why I did this is because I would like to use the RANS as my LES initial field, which corresponds to a fine mesh. Thank you in advance for your help!
