fer Model – Limitations: ? lack of error information ? can suffer from the ray effects – Benefits: ? Nongray models are dealt with by treating each band as a separate calculation ? Better quality solution than P1 and Rosseland Models, especially when there are optically thin regions in the domain – Example: ?
