We demonstrate the versatility of the multiphysics implementation by extending the code to model fully coupled continuum poromechanics. We verify the newly incorporated physics using standard benchmarks for a porous medium saturated with a slightly compressible fluid. The benchmarks include the 1-D consolidation problem as outlined by Terzaghi, Mandel\u2019s problem for the 2-D case, and Cryer\u2019s problem for the 3-D case. All three benchmarks have been added to the PyLith continuous integration test suite. We compare the closed form analytical solution for each benchmark against solutions generated by our updated code, and lastly, demonstrate that the poroelastic material formulation may be used alongside the existing fault implementation in PyLith.", "description": "34 p.", "publisher": { "@type": "Organization", "name": "Oxford Academic" }, "author": [ { "@type": "Person", "name": "Walker, Robert L.", "givenName": "Robert L.", "familyName": "Walker", "affiliation": [ { "@type": "Organization", "name": "University at Buffalo" } ] }, { "@type": "Person", "name": "Knepley, Matthew G.", "givenName": "Matthew G.", "familyName": "Knepley", "affiliation": [ { "@type": "Organization", "name": "University at Buffalo" } ] }, { "@type": "Person", "name": "Aagaard, Brad T. baagaard@usgs.gov", "givenName": "Brad T.", "familyName": "Aagaard", "email": "baagaard@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-8795-9833", "url": "https://orcid.org/0000-0002-8795-9833" }, "affiliation": [ { "@type": "Organization", "name": "Earthquake Science Center", "url": "https://www.usgs.gov/centers/earthquake-science-center" }, { "@type": "Organization", "name": "Geologic Hazards Science Center", "url": "https://www.usgs.gov/centers/geologic-hazards-science-center" } ] }, { "@type": "Person", "name": "Williams, Charles A.", "givenName": "Charles A.", "familyName": "Williams", "affiliation": [ { "@type": "Organization", "name": "GNS Science" } ] } ], "funder": [ { "@type": "Organization", "name": "Geologic Hazards Science Center - Seismology / Geomagnetism", "url": "https://www.usgs.gov/centers/geologic-hazards-science-center" } ] }, "OpenAlex": { "_id": "https://openalex.org/w4387113237", "abstract_inverted_index": { "SUMMARY": [ 0 ], "PyLith,": [ 1 ], "a": [ 2, 24, 56, 61 ], "community,": [ 3 ], "open-source": [ 4 ], "code": [ 5, 39 ], "for": [ 6, 55, 78, 85, 109 ], "modelling": [ 7 ], "quasi-static": [ 8 ], "and": [ 9, 82, 119 ], "dynamic": [ 10 ], "crustal": [ 11 ], "deformation": [ 12 ], "with": [ 13, 23, 60 ], "an": [ 14 ], "emphasis": [ 15 ], "on": [ 16 ], "earthquake": [ 17 ], "faulting,": [ 18 ], "has": [ 19 ], "recently": [ 20 ], "been": [ 21, 93 ], "updated": [ 22, 117 ], "flexible": [ 25 ], "multiphysics": [ 26, 34 ], "implementation.": [ 27 ], "We": [ 28, 46, 102 ], "demonstrate": [ 29, 121 ], "the": [ 30, 33, 38, 48, 68, 79, 86, 96, 104, 123, 131 ], "versatility": [ 31 ], "of": [ 32 ], "implementation": [ 35, 134 ], "by": [ 36, 74, 115 ], "extending": [ 37 ], "to": [ 40, 95 ], "model": [ 41 ], "fully": [ 42 ], "coupled": [ 43 ], "continuum": [ 44 ], "poromechanics.": [ 45 ], "verify": [ 47 ], "newly": [ 49 ], "incorporated": [ 50 ], "physics": [ 51 ], "using": [ 52 ], "standard": [ 53 ], "benchmarks": [ 54, 66, 91 ], "porous": [ 57 ], "medium": [ 58 ], "saturated": [ 59 ], "slightly": [ 62 ], "compressible": [ 63 ], "fluid.": [ 64 ], "The": [ 65 ], "include": [ 67 ], "1-D": [ 69 ], "consolidation": [ 70 ], "problem": [ 71, 77, 84 ], "as": [ 72 ], "outlined": [ 73 ], "Terzaghi,": [ 75 ], "Mandel\u2019s": [ 76 ], "2-D": [ 80 ], "case,": [ 81 ], "Cryer\u2019s": [ 83 ], "3-D": [ 87 ], "case.": [ 88 ], "All": [ 89 ], "three": [ 90 ], "have": [ 92 ], "added": [ 94 ], "PyLith": [ 97 ], "continuous": [ 98 ], "integration": [ 99 ], "test": [ 100 ], "suite.": [ 101 ], "compare": [ 103 ], "closed": [ 105 ], "form": [ 106 ], "analytical": [ 107 ], "solution": [ 108 ], "each": [ 110 ], "benchmark": [ 111 ], "against": [ 112 ], "solutions": [ 113 ], "generated": [ 114 ], "our": [ 116 ], "code,": [ 118 ], "lastly,": [ 120 ], "that": [ 122 ], "poroelastic": [ 124 ], "material": [ 125 ], "formulation": [ 126 ], "may": [ 127 ], "be": [ 128 ], "used": [ 129 ], "alongside": [ 130 ], "existing": [ 132 ], "fault": [ 133 ], "in": [ 135 ], "PyLith.": [ 136 ] }, "apc_list": { "value": 2590, "currency": "GBP", "value_usd": 3176, "provenance": "doaj" }, "apc_paid": null, "authorships": [ { "author_position": "first", "author": { "id": "https://openalex.org/A5052326517", "display_name": "Robert L.
