SimpsoniiiPrefaceIwouldliketothankmydoctoralsupervisorProf. Dr. Claus-DieterMunz,whomanaged to spark my interest in the field of numerical methods already in myyears of study. He supported and arranged my stay in Ann Arbor, Michigan,USA, where I wrote my diploma thesis under theinspiring supervision of Prof.Philip L. Roe. After that, I received a lot of support and thought-provokingimpulses from him during my time as a Ph.D. candidate at the IAG. There,especially the informal and creative working environment left much space forthe realization of own ideas.Also many thanks to my colleagues at the IAG, they were always availablefor discussions, offered a lot of input and made my time at the institute a veryenjoyableone.
