ZWSim – Structural Simulation
ZWSim Structural is a simulator that integrates both modelling and simulation. Using the finite element method (FEM), it simulates the physical behaviour of structures.
Solving structural mechanics problems, it allows engineers in different industries to assess the suitability of their structural design.
WSim Structural will help your engineers make faster and better decisions thus reducing R&D time and costs.

Advanced Algorithms for Efficient and Accurate Simulation
Multiple matrix algorithms and the eigenvalue extraction method help bring more accurate simulation results faster.
Friendly and Easy-to-Use
Clear workflow and friendly Graphical User Interface (GUI) make it easy for you to get started straight away.

High Compatibility for Seamless Data Exchange
20+ standard and commercial formats are supported, enabling you to import and export files with ease.
Powerful Modelling Capability
With our self-developed Overdrive kernel, parametric modelling and solid & surface hybrid modelling are available for faster and more robust modelling.

High-Quality and Efficient Meshing
The Hybrid Advancing-Front & Delaunay Mesh Generation has been adopted to support the generation of high-quality 1D/2D/3D meshes, and even tens of millions of meshes.

Many Different Types of Meshes Supported
Triangle, quadrilateral, tetrahedral, hexahedral and other types of meshes can be generated, fitting different types of solvers.
Different Constraints and Loads
Constraints like Fix Geometry, Roller/Slider, Fixed Hinge, structural loads like Force, Pressure, Torque, and thermal loads like Temperature, Heat Power, Heat Flux are accessible, to better simulate the actual environment.

Customizable and Reusable Materials
You can customize the properties of materials according to your specific needs, and add them to the library for reuse conveniently.
Effective Checking for Higher Precision
The correctness of geometry, materials, constraints, loads, meshes, etc. can be checked before running the simulation, increasing the accuracy of results.
