the warning above is OK, it's just saying that the particular inflow point i,j,k 739 ,104, 62 does not have a ghost cell on the xp face. But for that bc (bc 1) there are 7 valid cells.
Pre should only give a fatal error when there are no valid cells for a particular bc.
So look at all the lines beginning with bcset_size(n),n and if the 1st number is 0 that is your problem bc.
