Current FEA software/Comparison to Ansys

Click For Summary
SUMMARY

The discussion focuses on the search for alternative Finite Element Analysis (FEA) software due to an expired Ansys license, specifically for applications involving large deformation analysis, explosive simulations, and composite material failure. The user identifies LS-DYNA as a strong candidate due to its capabilities and compatibility with Ansys Workbench. Additionally, WelSim is mentioned as a user-friendly option worth exploring. The user seeks recommendations for other FEA tools that meet their criteria.

PREREQUISITES
  • Understanding of Finite Element Analysis (FEA) principles
  • Familiarity with large deformation analysis techniques
  • Knowledge of composite material behavior in simulations
  • Experience with Ansys Workbench interface
NEXT STEPS
  • Research LS-DYNA capabilities for large deformation and explosive simulations
  • Explore WelSim features and user interface for FEA applications
  • Investigate other FEA software options such as Abaqus and COMSOL Multiphysics
  • Review case studies on composite material failure analysis using FEA tools
USEFUL FOR

Mechanical engineers, simulation specialists, and anyone involved in FEA applications, particularly those transitioning from Ansys or seeking user-friendly alternatives for complex simulations.

Hi all,

This is my first post on this forum. I am located in Australia working as a mechanical engineer. Our Ansys License has expired (Technical support no longer available- Product purchased outright), and for some reason it doesn't allow the setting of 'large deflections' to be turned on (I'm quite sure this is because we have only the EMAG(electromagnetic) licence).

So it is for this reason I am currently investigating alternative FEA software to Ansys. Or I may renew our Ansys License, depending on what is the best solution.
Here are my required criteria:


  • For doing a large deformation sort of analysis where non linear material effects come into play; stamping simulations
  • Simulating a large explosion in a pressurised enclosure to see when the shell fails
  • Simulating composite materials and their failure limit
  • From what I have searched LS Dyna Seems like the best solver for my needs. It also seems to work directly from Ansys Workbench, which definitely is nice too.

Are there any other alternatives that are as user friendly that are worth investigating?

Thank you all in advance.
