Key Use Cases
What is ANSYS Composite PrepPost (ACP)
Complete composite FEA — from layup definition to certified failure maps
ANSYS Composite PrepPost (ACP) is the dedicated composite structure analysis module within ANSYS Workbench. It consists of two components: ACP Pre — the pre-processor for defining ply orientations, thicknesses, fibre angles, and stacking sequences on the 3D FEA model; ACP Post — the post-processor that computes ply-by-ply failure analysis using the full range of composite failure criteria.
ACP is the mandatory tool for any serious composite structural certification in aerospace (CS-25/FAR-25), defense, and wind energy. It enables the level of detail — ply-by-ply Reserve Factor maps, delamination energy release rates, draping simulation — that standard ANSYS Mechanical cannot provide for composite laminates. CADFEM Ukraine provides official ACP licenses, English-language composites training, and FEA consulting for Ukrainian and international composite engineering companies.
Graphical layup editor on 3D geometry
ACP Pre's Graphical Layup Editor defines ply orientations, thicknesses, and stacking sequences directly on the 3D geometry using Rosette coordinate systems — including automatic Geodesic Draping that simulates the real fabric deformation during layup on curved surfaces.
5+ failure criteria in one post-processor
ACP Post computes Reserve Factor (RF) and Inverse Reserve Factor (IRF) maps using all leading failure criteria: Tsai-Wu, Tsai-Hill, Hashin 2D/3D, Puck, and LaRC — layer by layer across the entire FEA model in a single analysis run.
Delamination analysis: VCCT and CZM
For aerospace certification (CS-25 / ASTM) and offshore structural assessments: VCCT (Virtual Crack Closure Technique) computes energy release rates G1, G2, G3 at an existing delamination front; CZM (Cohesive Zone Model) simulates progressive delamination growth.
Sandwich structures and panel optimization
Full sandwich panel analysis: CFRP or GFRP skins, foam or honeycomb core (Rohacell, Nomex, aluminum honeycomb). Failure criteria include core transverse shear, wrinkling, and skin debonding — critical for aircraft panels, UAV structures, and yacht hulls.

CADFEM Ukraine is the sole authorized ANSYS Channel Partner in Ukraine. We provide official ACP licenses with full technical support, English-speaking composites engineering team, training, and simulation consulting. Contact us for a commercial proposal.
Pricing
How much does ANSYS ACP (Composite PrepPost) cost?
ACP is included in ANSYS Mechanical Enterprise, or available as an add-on to ANSYS Mechanical Premium. Pricing depends on license type (lease or perpetual) and the base Mechanical license level. Submit a request for an individual quote.
Needs Mechanical
Does ANSYS ACP require ANSYS Mechanical?
Yes. ACP Pre and ACP Post work as extensions within ANSYS Workbench alongside ANSYS Mechanical. ACP Pre creates the layup model and passes it to Mechanical for FEA; ACP Post receives Mechanical results and performs failure analysis. ACP cannot operate without an ANSYS Mechanical license.
License options
What ANSYS Mechanical license tier is needed for ACP?
ACP (Composite PrepPost) is included in ANSYS Mechanical Enterprise. It is available as an add-on to ANSYS Mechanical Premium. For delamination analysis (VCCT, CZM), the ANSYS Fracture Mechanics Add-on is additionally required. CADFEM Ukraine will recommend the right configuration for your composite engineering workflow.

+38 (050) 454-37-54What is ANSYS Composite PrepPost (ACP) and what problems does it solve?
+
ANSYS Composite PrepPost (ACP) is the specialized ANSYS Workbench module for analysing fibre-reinforced laminated composite structures. ACP Pre handles the pre-processing: defining ply orientations, thicknesses, fibre angles, and stacking sequences on a 3D FEA mesh — including Geodesic Draping for accurate draping simulation on curved surfaces. ACP Post handles the post-processing: computing ply-by-ply Reserve Factors using Tsai-Wu, Hashin, Puck, and other criteria; identifying failure modes; and analysing delamination. Without ACP, standard ANSYS Mechanical cannot correctly represent the directional stiffness and failure behaviour of laminated composites.
What failure criteria does ANSYS ACP support?
+
ACP Post implements all industrially significant composite failure criteria: Tsai-Wu (quadratic polynomial — most widely used in industry); Tsai-Hill (maximum work theory); Hashin 2D and 3D (distinguishes fibre tensile/compressive failure from matrix failure — required for aerospace); LaRC (NASA Langley Research Center criteria); Puck (most accurate for matrix cracking direction prediction). All criteria output Reserve Factor (RF) and Inverse Reserve Factor (IRF) maps layer by layer across the full component.
How does ACP handle draping on curved surfaces?
+
ACP Pre uses Geodesic Draping — a simulation of the physical fabric draping process where the fabric conforms to the curved surface geometry with realistic shear deformation. Starting from a seed point and direction, the algorithm propagates the fibre angle across the surface, computing the actual local fibre orientation at every mesh node. This is more accurate than manually specifying a global orientation, especially for complex doubly-curved surfaces like helicopter blade roots, nose cones, and pressure vessel domes.
How does ANSYS ACP perform delamination analysis?
+
ACP Post, combined with the ANSYS Fracture Mechanics Add-on, implements two delamination methods: VCCT (Virtual Crack Closure Technique) — post-processes an existing interface crack to compute energy release rates G1 (mode I opening), G2 (mode II sliding), G3 (mode III tearing). Used for certification compliance (CS-25, ASTM E647). CZM (Cohesive Zone Model) — uses cohesive contact elements that progressively degrade, simulating crack initiation and growth from an undamaged interface. Used for predicting delamination onset and propagation trajectory.
Can ANSYS ACP optimise ply angles and stacking sequences?
+
Yes. ACP integrates with ANSYS optiSLang for parametric optimisation: ply angles (0°, ±15°, ±30°, ±45°, 90° or continuous), ply count per orientation, ply drop-off locations, and stacking sequence are defined as design variables. Objective functions include minimum laminate weight, maximum Reserve Factor, maximum bending stiffness EI, or minimum vibration frequency. Constraints include manufacturability rules (maximum angle change between adjacent plies, balanced symmetric layup requirements). The result is an optimal laminate schedule that meets all strength, stiffness, and weight requirements.
Does CADFEM Ukraine support ANSYS ACP in English for aerospace and defense?
+
Yes. CADFEM Ukraine provides all ACP services in English: official license procurement, technical support, composite structure simulation consulting (CS-25 compliance, UAV structures, wind blades), and training courses.
