In this work, we extended our recently developed open-source multi-graphics processing unit (GPU) full-wave simulator, UltraWave, to support simulations of acoustic and elastic absorption. Acoustic absorption with arbitrary power-law frequency dependence was modeled using optimized relaxation processes. Elastic absorption was modeled through Kelvin-Voigt viscoelasticity, with damping terms derived from compressional and shear absorption coefficients. For acoustic absorption with a power-law exponent of 1.5, the maximum normalized mean absolute error relative to theoretical signals was 0.63%. For elastic absorption with a power-law exponent of 2, the maximum normalized mean absolute difference compared to k-Wave was 0.14%. Additionally, UltraWave demonstrated substantial computational efficiency, requiring only 5 seconds on the same GPU compared to 14 minutes and 40 seconds needed by k-Wave. These results showed that our numerical modeling of acoustic and elastic absorption is accurate and highly efficient.","journal":null,"year":2025,"id":578596,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9445,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":673511,"name":"Yun Jing","orcid":"0000-0003-2960-5292","position":1,"is_corresponding":false},{"id":259399,"name":"Aiguo Han","orcid":"0000-0001-7606-9221","position":2,"is_corresponding":false},{"id":1188703,"name":"Zixuan Tian","orcid":null,"position":0,"is_corresponding":true}],"reference_count":22,"raw_metadata":null,"created_at":"2026-07-19T02:58:24.957414Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
