Cathodic Protection, AC and DC threats share one pipeline — so why model it twice?

Pipeline integrity engineers face two very different electrical threats on the same asset: AC interference from HVAC power lines along the right-of-way, and DC corrosion from cathodic protection and stray-current sources.

Historically that meant two models, two datasets, two tools — and every geometry fix or field-data update had to be redone in both. The DC & AC Bundle removes that split: one geospatial model, built once, feeds both analyses.

Three tools, one continuous workflow

Build the model once, then run both the AC and the DC study from it
Elsyca Model Composer
Build

The GIS-based model-generation layer. Import KML, Shape or CSV, batch-import many formats at once, assign coating and soil resistivity directly to branches, and save the whole project to a reusable .emc file. Ships with IRIS and CatPro.

Elsyca IRIS
Solve the AC

Inductive and Resistive Interference Simulator. Computes induced voltages, touch/step potentials, ground potential rise and AC current densities under normal load and fault conditions — with automated tower-by-tower fault simulation and automatic arcing-risk assessment.

Elsyca CatPro
Solve the DC

Cathodic protection and DC stray-current analysis. Combined BEM-FEM solver for off-/on-/IR-free pipe-to-soil potentials, radial and axial currents and voltage attenuation across multi-pipeline, congested and DC-traction/HVDC-interference environments.

The workflow: From raw GIS data to a defensible AC + DC assessment

One field-data file powers both solvers. AC and CP measurements stay together, with units auto-converted for each study.
Model

Import routings by exact GPS coordinates. No limit on pipelines, power lines or mitigation systems.

Enrich & calibrate

Assign coating, soil resistivity, tower & rectifier data. Multi-UTM-zone detection catches geospatial issues early.

Analyze — AC

Automated fault simulation across every tower; arcing risk, step voltage and GPR at your points of interest.

Analyze — DC

Pipe-to-soil potentials, stray-current interference and CP performance across the same network.

Review & Share

Load previous results instantly, explore in viewer-only mode, export to Google Earth and SVG.

Model your pipeline network once, then assess AC interference and cathodic protection from the same GIS model. Model Composer builds it, IRIS solves the AC, CatPro solves the DC — no rebuild, no re-entry, one source of truth.

  August 2026 release  

The bundle just got faster, safer and easier to share

Re-engineered, fully parallelised solvers — same trusted accuracy, a fraction of the wait.

Inductive study

13×

5.5 min → 26 s

Resistive fault + soil update

5.5 min → 40 s

CatPro two-layer soil

14×

5.3 min → 23 s

Dramatically faster solvers

Fully parallelised inductive and resistive solvers with a modern 64-bit build that lifts old memory limits — run bigger, more realistic models. Results identical, only the waiting is gone.

 IRIS & CatPro 

Automatic arcing-risk analysis

A fully automated, two-step assessment during resistive fault simulations — tower-to-pipeline distance (Sunde) combined with critical arc voltage, inputs gathered automatically, one summary file per faulted tower.

 IRIS 

Bigger, faster fault simulations

New solver options — "Faulted Power Line only" and "Towers inside the Interference Zone only" — shrink the model on the fly while leaving your master model untouched.

 IRIS 

Step voltage & GPR at points of interest

Automatically computed at user-defined Special Points — test posts, valves, assets — right where people and equipment are, with no separate manual analysis.

 IRIS 

Instant results review

Load previously computed steady-state (IRIS) and DC (CatPro) results straight from the results folder, branches and connections restored automatically. Pick up exactly where you left off.

 IRIS & CatPro 

Viewer-only mode

Load and explore results without a solver license (dedicated viewer license) — share with colleagues, managers and clients while keeping solver licenses free for the engineers who model.
