CFD Online Discussion Forums - mergeMesh error!!

Dear foamers

I have two separate domains which are to be merged together. But the errors shows below:
Code:
Master:      "kklomega_Ogrid_chord100_402x141x2"  region region0               

mesh to add: "kklomega_Ogrid_chord100_402x141x2_tunnel"  region region0        



Create Times

Reading master mesh for time = 0

Create mesh                     



Reading mesh to add for time = 0

I am using OF2.1.0. Do you have some ideas to solve this problem? Thanks a lot!
