Three membrane mechanics simulations wrapped as process-bigraph
Processes using discrete differential geometry. Each configuration demonstrates
a distinct biophysical scenario with interactive 3D visualization.
A spherical vesicle (icosphere) deflates to 50% of its initial volume under harmonic osmotic pressure. Bending rigidity maintains the smooth spherical shape as the membrane contracts. This models osmotic shock in biological vesicles.

Membrane Patch Bulging
Flat hexagonal membrane inflated by pressure
A flat hexagonal membrane patch with fixed boundary edges is inflated by constant osmotic pressure, forming a dome. This models local membrane deformation events such as bleb formation or pressure-driven bulging in confined geometries.

Tubular Constriction
Cylinder narrowing under volume reduction
A cylindrical tube constricts as osmotic pressure drives volume reduction to 60% of its initial value. The tube narrows uniformly while pinned boundary conditions hold the ends. This models membrane tubule dynamics in endoplasmic reticulum networks.
