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.

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.
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.
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.
Import routings by exact GPS coordinates. No limit on pipelines, power lines or mitigation systems.
Assign coating, soil resistivity, tower & rectifier data. Multi-UTM-zone detection catches geospatial issues early.
Automated fault simulation across every tower; arcing risk, step voltage and GPR at your points of interest.
Pipe-to-soil potentials, stray-current interference and CP performance across the same network.
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.
Re-engineered, fully parallelised solvers — same trusted accuracy, a fraction of the wait.
5.5 min → 26 s
5.5 min → 40 s
5.3 min → 23 s
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
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
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
Automatically computed at user-defined Special Points — test posts, valves, assets — right where people and equipment are, with no separate manual analysis.
IRIS
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
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.
IRIS & CatPro
Inductive & resistive interference
Study inductive and resistive interference between buried pipelines, railways and utilities and transmission power lines — then verify mitigation designs for compliance with international standards.
Cathodic protection & DC stray current
Design, optimize and troubleshoot cathodic protection installations and analyze DC stray-current interference across complex, congested pipeline networks.
Proven daily by Elsyca's own consultants and a loyal customer base, refined on real user feedback.
Results that correspond with reality across hundreds of studies; CP solver co-developed with Gasunie.
Rich visualization, Google Earth / SVG export and clear charts for both AC and DC results.
Supports compliance with local and international standards (NACE/AMPP, EN 12954, ISO 15589…).
