WELSIM (WelSimulation) is a general-purpose, 3D engineering simulation and Finite Element Analysis (FEA) software. It provides a user-friendly graphical interface designed primarily as a pre- and post-processor that integrates with popular open-source solvers like CalculiX, Elmer FEM, FrontISTR, and OpenRadioss.
The standard tutorial workflow for setting up and running a structural simulation project in WELSIM involves five core steps. 🛠️ Core Simulation Tutorial Workflow 1. Project Initialization & Material Definition
New Project: Starting the application initializes a default simulation project tree.
Unit System: Select your preferred units (e.g., metric) via the Units tab before configuring properties.
Material Properties: Double-click the material object to import presets (like Aluminum or Copper Alloy) from the Predefined Material Library or manually input values like Young’s Modulus and Poisson’s Ratio. 2. Geometry Setup
Import CAD: Import 3D CAD geometries using standard formats like .STEP or .IGES files.
Material Assignment: Select individual bodies or parts from the object tree and assign your designated materials through the properties dropdown panel. 3. Meshing (Grid Generation)
