importing a data file with different mesh size
 

Dear all;

I have a question about importing a data file exported from an outlet boundary condition. At first, I solve flow through a duct with pressure outlet B.C. Then, I export outlet velocity data file. At this time, I want to import outlet velocity data file to the inlet of second duct. It is noticeable that the mesh size at the outlet of first duct is different from that at the inlet of second duct. Please help me to solve this problem.
