Problem

What is HAMMER's calculation engine (numerical solver) based upon?

Solution

Methodology

HAMMER uses the Method Of Characteristics. This is often considered gold standard for numerical simulation of hydraulic transients because it continues the most widely researched and extensively validated method world-wide. See more in the link below.

Rectangular vs. Staggered grid

HAMMER's Method of Characteristics implementation uses a rectangular grid approach. (not a staggered grid.)

Courant stability criterion

See: Do the interpolation schemes used by HAMMER satisfy the Courant stability condition?
