Key Use Cases
What is ANSYS nCode DesignLife
From FEA stress fields to certified fatigue life predictions
ANSYS nCode DesignLife is the specialized fatigue post-processor developed by HBK (formerly HBM nCode), integrated into the ANSYS Workbench environment. It takes stress and strain results from ANSYS Mechanical FEA and combines them with real operational load spectra to compute fatigue damage, life in cycles, Reserve Factor, and Safety Margin at every point of the component.
Unlike the simplified Fatigue Module in basic ANSYS Mechanical, nCode DesignLife is built for industrial-grade fatigue certification: it processes real time-history load data from road tests, flight recorders, and sea state measurements; implements all major damage criteria; and generates outputs directly usable in certification reports for aerospace (CS-25), automotive (FMVSS), and offshore (ASME, API) standards. CADFEM Ukraine provides official nCode licenses and English-speaking fatigue support in Ukraine.
Real load spectra — not simplified sine waves
nCode DesignLife processes actual time-history load data from physical tests (strain gauges, accelerometers) or standard databases (RLDA, EUROCYCLE). Rain-Flow cycle counting extracts fatigue cycles from real-world load sequences.
All major damage criteria in one tool
S-N (stress-life, HCF), ε-N (strain-life, LCF), Critical Plane methods (Findley, Dang Van for multiaxial), weld fatigue (BS7608, IIW, FKM), vibration fatigue (PSD: Dirlik, Narrow Band), and TMF — all within one nCode DesignLife license.
Seamless ANSYS Mechanical integration
nCode DesignLife connects directly to ANSYS Workbench as an additional analysis system — FEA stress fields from Mechanical pass to nCode automatically. No manual file export. Supports Abaqus, Nastran, and LS-DYNA results as well.
Component-level Reserve Factor maps
Results visualized as fatigue life (cycles to failure), damage (D = Σ n/N per Miner-Palmgren), Reserve Factor (RF = 1/IRF), and Safety Margin — layer by layer for composites, weld class by weld class for welded structures.

vs Fatigue Module
How does nCode DesignLife differ from the built-in Fatigue Module in ANSYS Mechanical?
ANSYS Mechanical Fatigue Module handles simple S-N analysis at constant amplitude — suitable for basic checks. nCode DesignLife is the industrial-grade tool: real time-history load spectra (Rain-Flow counting), multiaxial critical plane criteria (Findley, Dang Van), weld fatigue per BS7608/IIW, vibration fatigue (PSD), and TMF. For certification-grade analysis and complex real-world loading — nCode DesignLife is required.
Supports
What FEA solvers does nCode DesignLife support?
nCode DesignLife natively reads results from: ANSYS Mechanical (RST files — direct Workbench connection), Abaqus (ODB files), MSC Nastran (OP2 files), and ANSYS LS-DYNA (d3plot). For most users, the ANSYS Workbench direct connection is used — stress fields pass from Mechanical to nCode automatically.

+38 (050) 454-37-54What is ANSYS nCode DesignLife and why is it needed?
+
ANSYS nCode DesignLife is the industry-leading fatigue life prediction software, developed by HBK (formerly HBM nCode). It takes FEA stress and strain fields from ANSYS Mechanical and combines them with real-world load spectra to predict fatigue life — how many cycles or hours a component will survive before crack initiation. It is used wherever component fatigue failure is a critical engineering risk: aerospace, automotive, oil & gas, wind energy, and defense. CADFEM Ukraine provides official nCode licenses and English-speaking fatigue engineering support.
What is a load spectrum (time-history) and how does nCode process it?
+
A load spectrum (time-history) is a recording of how a load variable (force, moment, acceleration, pressure) varies with time during real operation. It is measured by strain gauges, load cells, or accelerometers during physical test events (road drives, flight tests, sea trials). nCode DesignLife processes this spectrum using Rain-Flow cycle counting — extracting all fatigue cycles defined by their amplitude and mean — and then computes cumulative fatigue damage at every FEA node using the Miner-Palmgren linear damage rule.
What is the difference between S-N and ε-N fatigue analysis in nCode?
+
S-N (Stress-Life): works with stress amplitudes, uses Wöhler curves from material databases. Appropriate for High-Cycle Fatigue (HCF >10⁴ cycles) where stresses remain elastic. Widely used in aerospace, machinery, and structural applications. ε-N (Strain-Life): works with strain amplitudes including plastic strain, uses Coffin-Manson / Ramberg-Osgood parameters. Required for Low-Cycle Fatigue (LCF <10⁴ cycles) where yielding occurs — turbine rotors, notched components, welded joints under high stress. nCode DesignLife implements both in the same interface.
How does nCode DesignLife perform weld fatigue assessment per BS7608?
+
nCode DesignLife implements BS7608 (UK standard), IIW Recommendations, and FKM-Guideline for weld fatigue. The user assigns a weld class (A through G in BS7608) to each weld feature in the FEA model. nCode then extracts the local structural stress at the weld toe, applies the load spectrum, counts cycles by Rain-Flow, and computes damage using the class-specific S-N curve. Results include life cycles per weld location, enabling identification of the fatigue-critical weld in a complex assembly.
What is thermomechanical fatigue (TMF) and does nCode DesignLife support it?
+
Thermomechanical fatigue (TMF) occurs when a component is simultaneously subjected to thermal cycling (large temperature swings) and mechanical loading at elevated temperature — typical of gas turbine combustor liners, exhaust manifolds, and turbocharger housings. nCode DesignLife TMF module uses a coupled Mechanical-Thermal FEA workflow: ANSYS Mechanical computes temperature-dependent stress and strain fields; nCode applies a TMF damage model that accounts for creep damage, oxidation, and thermal fatigue interaction. This gives a more accurate life prediction than simple isothermal LCF analysis.
Does CADFEM Ukraine provide fatigue engineering support in English?
+
Yes. CADFEM Ukraine's fatigue engineering team provides all services in English: nCode DesignLife license procurement, technical support, training courses, and fatigue simulation consulting with English-language deliverables. This makes us the preferred partner for international engineering companies, Ukrainian aerospace and defense contractors working on export projects, and organizations requiring fatigue analysis reports for international certification bodies.
