Modeling a LFA Rapid Detection Test

This example models a lateral flow assay for the detection of coronavirus antibodies in a 2D geometry. The chemical species are homogeneously distributed over the membrane thickness.

A Large-Strain Poroviscoelastic Model of Brain Tissue

This example demonstrates how to set up a fully coupled poroviscoelastic model of biological tissues. The model is benchmarked by simulating a cyclic uniaxial tension–compression test on human brain tissue.

Linear Biphasic Poroelasticity

This example demonstrates how to use the Poroelasticity multiphysics coupling between the Solid Mechanics and Darcy’s Law interfaces to model linear poroviscoelastic behavior of soft biological tissues.

The Mandel–Cryer Effect

Cryer’s problem is a three-dimensional consolidation benchmark where a porous sphere is subjected to a uniform boundary pressure. The pore pressure at the center of the sphere rises due to the Mandel–Cryer effect, which is modeled using the Poroelasticity multiphysics interface.
