[esp-r] CFD grid error

[nalin at me.iitb.ac.in]

Hello all

I am trying to learn the CFD module of ESP-r, for this I have modeled a
simple room with two window openings on opposite walls. I have checked the
grid many times but still ESP-r gives the error of some boundary cells not
being defined as boundary condition or are defined more than once.I did
not find any overlapping cells or any left out (not defined) cells so am I
doing something else wrong???

Sincerely

Nalin
