How this service works
Replay a supplied ideal waterhammer wave grid with explicit boundary velocities.
Output
Returns the simulated pressure head and velocity fields across the characteristic grid at the requested sample time steps, computed using the ideal (frictionless) method-of-characteristics approach with the supplied boundary conditions.
Example use cases
Pipeline pressure surge verification
“I need to verify a waterhammer simulation for a 500-meter frictionless pipe with wave speed 1000 m/s, gravity 9.81, initial heads all at 100 meters across 5 nodes, initial velocities of 2.0 m/s, reservoir head 105 meters, outlet velocities dropping to zero over 3 steps, sampled at steps 0, 1, and 2 — can you replay the characteristic grid and give me the head field?”
Hydraulic transient teaching demonstration
“Show me the pressure head wave propagation for a classic frictionless waterhammer scenario: 200-meter pipe, wave speed 800 m/s, gravity 9.81, 3-node initial heads at 60 meters, initial velocities 1.5 m/s, reservoir head 62 meters, outlet velocity goes from 1.5 to 0 in one step — sample at steps 0 and 1 so I can illustrate the method of characteristics.”
Boundary condition sensitivity check
“Run a frictionless waterhammer characteristic grid for a 2000-meter pipeline with wave speed 1400 m/s, gravity 9.81, 5 initial head nodes at 80 meters, initial velocities 0.5 m/s, reservoir head 82 meters, and outlet velocities of 0.5 m/s for 4 steps, sampling at steps 2, 3, and 4 — I want to check how the reservoir and outlet boundaries affect the mid-pipe pressure heads.”

Endpoint
POSThttps://detect.halowerk.com/v1/F-TD2000-GEO-INDUSTRY-B008/frictionless-waterhammer-characteristic-grid-boundary-transcript?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, frictionless method-of-characteristics waterhammer grid replay with explicit boundary control — particularly when you have a pre-defined ideal wave scenario and need head/velocity fields at specific time steps. Prefer this over full friction-inclusive solvers when validating ideal theory or teaching MOC concepts.
Side effects
- Mismatched array lengths between initial_heads and initial_velocities cause validation errors
- outlet_velocities array shorter than the required number of time steps returns an error
- wave_speed or length out of allowed bounds returns a 400 validation error
- Incompatible claim object causes rejection
- Payment not provided or insufficient USDC results in 402 Payment Required
