A resolution of singularities of Drinfeld compactification with an Iwahori structure

This paper considers a tiny modification of Justin Campbells construction of the Kontsevich compactification in cite{[Camp]}. We construct a resolution of singularities of Drinfeld compactification with an Iwahori structure and use it to prove the universally local acyclity of !-extension D-module on the Drinfeld compactification with an Iwahori structure.
