Crystallization

Nucleation & yield. This multi-solver chains 2 solvers into a single guided workflow — run each step in order and carry the result forward.

Chemical Equilibrium (Le Chatelier)Live
A (reactant)0.67 M
B (product)1.33 M

Controls

A reversible reaction A ⇌ B settles where forward and reverse rates balance. Add reactant or raise temperature and watch the equilibrium shift to relieve the stress.

Governing equation

Reading this result: Effective K is near 1, so A and B coexist in comparable amounts and a small stress can tip the balance either way.

Phase Diagram (Water)Live

Controls

Presets

A phase diagram maps which state — solid, liquid, or gas — a substance takes at each temperature and pressure. The lines are phase boundaries; cross one and the material transforms. All three meet at the triple point, and the liquid-gas line ends at the critical point beyond which liquid and gas become indistinguishable.

Phaseliquid
Temperature25 °C
Pressure100 kPa

Governing equation

Reading this result: Liquid: warm enough to melt yet below the boiling line at this pressure, so the stable state is liquid water.

Frequently asked questions

What is the Crystallization multi-solver?
Crystallization is a guided workflow that chains 2 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.
Is it free to use?
Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.
