Description

Problem

All existing chamber blocks in svZeroDSolver assume linear (or effectively linearized) filling in diastole, typically via a time-varying elastance form P(t)=E(t)[V(t)−Vrest(t)].
This makes it hard to reproduce well-established nonlinear P–V behavior in atria/ventricles during filling.

Solution

Implement a new chamber model with nonlinear passive filling behavior using exponetial equation.

Research direction

Start by reviewing the existing chamber blocks in the svZeroDSolver repository and how their diastolic filling behavior is represented. The work is done when a new chamber model supports the requested nonlinear passive filling behavior and integrates with the existing solver; the issue does not name specific files or tests.
