Zero Pressure with mapFields
 
Hello all,

I am using the results from a URANS simulation as initial values for LES. I use mapFields utility for this.

1) If I use mapFields with ---> source: Coarse mesh, target: Fine mesh
I get he values that make no sense (Zero pressure, negative k and omega, 1000 velocity...)

2) If I use mapFields with ---> source: Fine mesh, target: Coarse mesh.
Then it works fine!

Can anybody explain me why?? Is is a bug?
I need to use the data from the URANS simulation for LES. Is there any other way I can do it without using mapFields?

Thanks a lot =)
Any idea / comment will be more than welcome
