Abstract

fetched live from OpenAlex

Recently, an implementation of the mixed pressure displacement {u,P} formulation for poroelastic materials using the theory of hierarchical elements has been proposed. It has been shown that poroelastic hierarchical elements allow for an important reduction of the number of degrees of freedom required for the modeling of a porous material in three dimensions, compared to linear finite elements. In this paper, the coupling of a porous material modeled with hierarchical elements and an elastic domain modeled with finite elements or a fluid modeled with hierarchical elements is presented. Non-coincident meshes are assumed. Continuity of the fields is ensured by using a two-field hybrid formulation. The paper is organized as follows. The theory is first presented. The computation of fluid-structure coupling integrals over non-coincident meshes is then tackled. Numerical results are produced to show the accuracy and the performance of the proposed model for the modeling of an elastic-porous or a porous-fluid coupled system. Comparisons between numerical simulations and experiments are also presented in the case of a porous coated plate.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
