What is a CAx?

Computer-aided technologies (CAx) is the use of computer technology to aid in the design, analysis, and manufacture of products. Advanced CAx tools merge many different aspects of the product lifecycle management (PLM), including design, finite element analysis (FEA), manufacturing, production planning, product.

ZWSim Structural

Structural Simulator by Finite Element Method

ZWSim Structural is a structural simulator that integrates modeling and simulation. The finite element method (FEM), it simulates the physical behaviors of structures. Solving structural mechanics problems, it helps engineers in different industries assess the rationality of structural design, make faster and better decisions, and reduce R&D time and costs

With a self-developed Overdrive kernel, parametric modeling and solid & surface hybrid modeling are available for faster and better modeling.

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.

Multiple Types of Structural Simulation

Analyses of linear statics, buckling, frequency and mode shapes, steady-state heat transfer, and transient-state heat transfer are supported to meet different application requirements.

Abundant Types of Meshes

Triangle, quadrilateral, tetrahedral, hexahedral, and other types of meshes can be generated, fitting different types of solvers.

Customizable and Reusable Materials

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.

The simulation results can be displayed as plots, tables, animations, etc., or customized as you like. You can also probe the results and generate relevant reports
