The DYCO Solvers suite

DYCO is a suite of solvers able to compute high accuracy solutions to non-linear stock/flow potentials coupled equations, based on a nodal approach strategy.

Left: Elementary Cell, stock/flow coupled potentials (1 or N coupled potentials, also in series) - Right: example in the thermo-electric context

Main features

Nodal description of the considered network.
Non linear Onsager type coupling between forces & fluxes.
Steady, pseudo-unsteady & unsteady computations.
Handle local to global scales (i.e. from coarse-grain to fine tuning).
Possibly complex non-homogeneous structures and topologies.
Possibly anisotropic, discontinuous coupling coefficients; potentials and time dependence can also be included.
Allows for lighter/heavier computations and technological “optimization” !

Sample Results

We show below a short gallery of pictures obtained using the DYCO solver, in the thermo-electric context.

Sample 3D results including a non-homogeneous thermo-electric material with non-constant TE coefficients.

Sample 3D results for N-type junction with non-constant noisy TE coefficients.

In both cases, BC are Homogeneous Neumann and/or Non-Homogeneous Dirichlet. Each elementary cell is of the non-ideal (non-linear) type.

Sub-modules

A sub-module of DYCO shall be devoted to the numerical solution of coupled stock/flow potential in the ecological economics and biological contexts.

Yves D'Angelo, Christophe Goupil, Eric Herbert, Xanthippi Zianni, Louise Meteir, Aurélie Louis-Napoléon.
