Duration
2 days
Prerequisites
None
Software used
Ansys Mechanical
- FE checklist for validation and verification of simulations.
- Define simulation models appropriately with respect to the objectives
- Consider mesh requirements in the design of the model
- Check the plausibility of your simulation results
Description
As an engineer, you know that not every simulation model automatically delivers realistic results. Differences between system behavior and FE simulation results can occur. It’s important to know the causes of these differences.
In our training, you will learn how to improve the quality of your FE models. A systematic approach to model building, from the choice of load assumptions to proper meshing and evaluation of results, is crucial. You will learn how to adequately represent reality in relation to simulation objectives and how to take mesh requirements into account during model building. You will also learn to identify systematic errors and understand the options you have to achieve more accurate results. You will get an overview of the entire simulation process and the various control options. You will be able to efficiently assess your simulation results by considering plausibility and by performing manual calculations. With our FE checklist, you will be able to critically review your model and identify common errors early on.
This training is aimed at engineers and designers who want to deepen their FEA knowledge, as well as project managers who commission simulations and want to better understand and analyze the results.
