  THE WORK WILL FOCUS ON THE 3D IMPLEMENTATION OF THE PHASE 1 CHARM MESHER, WITH SOLUTION-ADAPTIVE ITERATION FOR CFD AND NON-CFD APPLICATIONS. THE PROPOSED 3D METHOD WILL INCORPORATE AND EXTEND A PREVIOUSLY DEVELOPED METHOD OF GENERATING FIELD-GUIDED HEXAHEDRAL ELEMENTS FROM A METRIC TENSOR FIELD. WHILE THE FUNDAMENTAL TECHNICAL APPROACH - A COMBINATION OF METRIC TENSOR CONDITIONING, METRIC-TRACING MESHER, AND CELL-PACKING MESHER - REMAINS THE SAME, THERE ARE MANY TECHNICAL CHALLENGES SPECIFIC TO THE 3D DOMAIN, INCLUDING THE FOLLOWING: - INVESTIGATION INTO CONDITIONING OF VOLUME METRIC TENSOR FIELDS - INVESTIGATION INTO THE TOPOLOGY (STRUCTURE) OF VOLUME METRIC TENSOR FIELDS - DEVELOPING ALGORITHMS FOR THE GENERATION, REPAIR, AND ADJUSTMENT OF STREAMSURFACE ARRANGEMENTS - DEVELOPING ALGORITHMS TO CONVERT STREAMSURFACE ARRANGEMENTS TO HEX-DOMINANT MESHES - DEVELOPING ALGORITHMS TO COMBINE STREAMSURFACE- AND PACKING-BASED MESHES - INVESTIGATION INTO DESIGNING THESE ALGORITHMS FOR MESH ADAPTATION RATHER THAN ADAPTIVE REMESHING - INVESTIGATION OF TIME AND STORAGE EFFICIENCY OF THESE ALGORITHMS IN A LARGE-SCALE PARALLELISM CONTEXT IN ADDITION TO THE ABOVE, THE GOAL IS TO GENERALIZE THE SOLUTION IN ORDER TO SUPPORT ITS PACKAGING AND COMMERCIALIZATION FOR A NUMBER OF PROBLEM SETS AND TARGET APPLICATIONS. THIS INCLUDES GENERALIZATION OF THE SOLVER-ADAPTIVE FRAMEWORK, CREATION OF APIS TO PROGRAMATICALLY EXPOSE CORE FUNCTIONS, AND PROVIDE UI ACCESS TO APPROPRIATELY CONTROL AND CONFIGURE THE APPLICATION.
