In particular, the reduced model is used to monitor the transfer of activity (e.g. mass, energy) from larger to smaller scales. When the activity transfer rate exceeds a prescribed tolerance, the algorithm refines the mesh accordingly. The algorithm was applied to the inviscid Burgers and focusing Schr\\\"odinger equations to detect singularities. We offer here a simple proof of why the use of a reduced model for mesh refinement is a good idea. We do so by showing that by controlling the transfer of activity rate one controls the error caused inevitably by a finite resolution.", "revisions": [ { "version": "v1", "updated": "2014-02-26T03:44:14.000Z" } ], "analyses": { "subjects": [ "65M50", "35L67", "76B99", "65M70" ], "keywords": [ "mesh refinement", "model reduction", "reduced model", "activity transfer rate exceeds", "algorithm refines" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1402.6402S" } } }
