ISPG is a fully Implicit Lagrangian Particle Galerkin approach solving Navier-Stokes equations considering viscosity, surface tension and contact angles in liquid. This is an efficient method to solve free-surface flow problems involving strong surface tension like solder reflow, adhesive flow, compression molding which bring challenges to existing CFD solvers. Adaptive ISPG is ISPG with Adaptive remeshing to cover a wide range of complex problems. This plugin will extend usage of Ansys Mechanical LS-DYNA to Adaptive ISPG, to simplify simulation set-up and solution directly from within Mechanical. ## Key Benefits - User-friendly Mechanical interface for Simulation set-up and solving - Quick Ramp-up time for existing Mechanical users - Easy to follow Documentation, Training and Examples ## Use Cases - Solder Reflow & Defects - Adhesive Flow Problems: - Underfill Simulation - Compression Molding ## Images ![AppImages](/sites/default/files/2025-06/001_AdaptiveISPGACTforLS-DYNA_1.0_AppImages_1.png "AppImages") AppImages ![AppImages](/sites/default/files/2025-06/002_AdaptiveISPGACTforLS-DYNA_1.0_AppImages_2.png "AppImages") AppImages ## Videos Adaptive ISPG ACT for LS-DYNA Example ## Latest version Adaptive ISPG ACT for LS-DYNA 2.6 Supported Ansys versions: 2025 R1, 2025 R2 [Download](/app/ansys-inc/adaptive-ispg-act-ls-dyna/2-6/download-app) Go to top Publisher![Publisher logo](/sites/default/files/%5Bdate%3Acustom%3AY%5D-%5Bdate%3Acustom%3Am%5D/ansys-part-of-synopsys-logos-full-color-rgb.jpg) Ansys Inc Support information Southpointe 2600 Ansys Drive, Cannonsburg, PA USA 724-746-3304
