FEMtools
simulate, validate, update, optimize
Modern product development faces increasing challenges. Products must be stronger, lighter, safer, and more cost-efficient, while incorporating new materials and meeting stricter design criteria. With FEMtools, we offer a powerful, versatile software suite that seamlessly integrates Finite Element Analysis (FEA), model validation, and optimization to deliver high-performance solutions.
There are six FEMtools configurations, each targeting different types of applications:
Each FEMtools configuration can be complemented with the following add-ons for integration with standard commercial FEA programs or for additional specialized functionality:
FEMtools Framework is a multi-functional platform for the development, integration, and automation of advanced engineering applications. It offers powerful tools such as data management, mesh generation, response analysis, and state-of-the-art visualization. With its integrated scripting language and API, users can automate processes and create custom applications.
Optional modules include standard finite element analysis (FEA) capabilities and support for external solvers such as NASTRAN, ANSYS, and ABAQUS, making FEMtools Framework ideal for both stand-alone use and process integration. It also provides unique capabilities for combining experimental and numerical data.
Applications:
FEMtools Framework delivers a robust and flexible foundation for all your engineering and analysis needs.
FEMtools Dynamics is a specialized configuration of FEMtools designed for advanced structural dynamics simulations. It offers tools for analyzing dynamic response, structural modifications, and frequency-based behaviors, enabling direct correlation with experimental results.
Key capabilities include:
FEMtools Pretest and Correlation simplifies modal test planning and ensures accurate alignment between finite element models and experimental results. With tools to simulate tests, engineers can determine the optimal points for excitation, suspension, and sensor placement, seamlessly transitioning from simulation to testing.
This solution enables precise correlation analysis to validate models and detect issues. Global correlation matches mode shapes, while local correlation highlights areas of poor agreement, revealing structural damage or modeling errors. By integrating experimental data like modal damping, FEMtools ensures simulations are as accurate as possible, enhancing methods like modal superposition.
Engineers can also scale test mode shapes to match analytical modes, creating consistency across data sources. These insights help refine finite element models, optimize test designs, and identify structural issues with confidence.
FEMtools Pretest and Correlation connects simulation and real-world testing, enabling engineers to validate models and improve structural accuracy with ease
An Integrated Solution for Structural Dynamics Simulation, Model
Verification, Validation and Updating
Core Capabilities of FEMtools Model Updating:
FEMtools Model Updating integrates seamlessly with tools for structural dynamics, pretest planning, and correlation analysis, providing a comprehensive solution for accurate simulations. By enabling model validation, refinement, and damage detection, FEMtools ensures simulations are reliable and aligned with real-world performance.
FEMtools Optimization integrates seamlessly with finite element analysis (FEA) to enhance existing designs or generate innovative new ones. By combining advanced optimization algorithms with FEA, this tool computes optimal design parameters based on applied loads, design constraints, and required structural performance.
This approach ensures more efficient and effective design improvements compared to traditional trial-and-error methods. FEMtools Optimization’s cutting-edge techniques maximize component performance while maintaining flexibility in defining problems. Its open architecture allows users to employ their preferred FE solvers or leverage FEMtools Dynamics solvers for re-evaluations.
Validated Optimization
When paired with FEMtools Model Updating, FEMtools Optimization offers the added advantage of validating and refining the initial finite element model using prototype test data before optimizing the structure. This ensures that optimization is grounded in accurate and reliable models, delivering superior design outcomes.
FEMtools configurations can be enhanced with add-on tools for integration with commercial FEA programs or advanced functionalities, ensuring seamless data exchange and specialized analysis capabilities.
FE Data Interfaces and Drivers: Directly integrate FEMtools into CAE workflows with interfaces for Abaqus, Ansys, LS-Dyna, MSC.Nastran, NX Nastran, OptiStruct, and SAP2000. Automate import, export, and re-analysis of models.
