Model and equations
$$t_s = B\left(\frac{V}{A}\right)^n$$
Chvorinov’s rule is an empirical relation where solidification time scales with a power of modulus V/A. Alloy, mold, superheat, and riser details need separate checks.
How to read it
The geometry view compares volume against cooling surface area.
The timeline checks whether riser solidification remains later than casting solidification.
The sensitivity plot shows how area and exponent change time.

🙋
When reading Casting Solidification Chvorinov, where should I look first? Moving Casting volume changes both the plots and the result cards.
🎓
Start with Solidification time, but do not treat the number as the whole answer. Use Casting modulus sketch to confirm the assumed state, then read Solidification timeline for the distribution or trend. The geometry view compares volume against cooling surface area.
🙋
I can see why Casting volume changes Solidification time. How should I judge the influence of Cooling area?
🎓
Move Cooling area in small steps and watch Modulus. That reveals which term is controlling the result. Chvorinov’s rule is an empirical relation where solidification time scales with a power of modulus V/A. Alloy, mold, superheat, and riser details need separate checks. A single operating point is not enough; sweep the realistic scatter range.
🙋
What is Modulus sensitivity for? It feels like the ordinary curve already tells the story.
🎓
Modulus sensitivity is for finding boundaries where the condition becomes risky or margin collapses quickly. The timeline checks whether riser solidification remains later than casting solidification. In Initial riser-modulus checks, the important question is often what happens after a small change, not only the nominal value.
🙋
So if Solidification time is within the target, can I accept the condition?
🎓
Treat this as a first-pass review. It helps with Comparing thickness changes against solidification time and Screening casting concepts before detailed simulation, but final decisions still need standards, measured data, detailed analysis, and vendor limits. The sensitivity plot shows how area and exponent change time.

FAQ
Start with Solidification time and Modulus. Then use Casting modulus sketch to confirm the assumed state and Solidification timeline to read distribution or bias. The geometry view compares volume against cooling surface area
Move Casting volume alone, then move Cooling area by a comparable amount and compare the change in Solidification time. Modulus sensitivity shows combinations where margin or performance changes quickly.
Use it for Initial riser-modulus checks. Instead of trusting a single point, widen the input range and check whether Solidification time keeps enough margin before moving to detailed analysis.
