However, these schemes require many points per wavelength in order to propagate waves with a reasonable amount of accuracy. In this work, the linear wave propagation characteristics of MacCormack-type schemes are investigated, and methods for greatly improving their performance are described and demonstrated.","isLessonsLearned":false,"disseminated":"DOCUMENT_AND_METADATA","publications":[{"submissionId":19970009353,"id":"d409bdae8f3a41e8bfc7dd2b55e2f7a0","publicationDate":"1996-12-01T00:00:00.0000000+00:00"}],"status":"CURATED","related":[],"downloads":[{"draft":false,"mimetype":"application/pdf","name":"19970009353.pdf","type":"STI","links":{"original":"/api/citations/19970009353/downloads/19970009353.pdf","pdf":"/api/citations/19970009353/downloads/19970009353.pdf","fulltext":"/api/citations/19970009353/downloads/19970009353.txt"}}],"downloadsAvailable":true,"index":"submissions-2026-06-11-04-51"}
