BETA CAE Launches New FEA Solver

Community-driven Eπilysis solver designed for structural, NVH, optimization and more.

The new release of BETA CAE Systems’ CAE suite is now available. The 16.0.0 release of ANSA and μETA is peppered with various new tools and functions, along with a new FEA solver they are calling Eπilysis. Pronounced “epilysis,” it is Greek for resolution.

The Eπilysis solver is available throughout what is now called BETA CEA Systems’ ANSA / Eπilysis / μETA suite. The solver was made with the help of CAE community participation. As a result, the solver is able to handle various solution types from structural, NVH (noise, vibration and harshness), optimization and more.

The 16.0.0 ANSA pre-processor will be compatible with previous versions of the software. This release focuses on processes, performance and improvements in user productivity.

For instance, the parts manager has been replaced with a model browser. This browser will allow users to view all the information associated with a part or group in one location regardless of which tool the information is associated with.

Some interesting ANSA improvements include:

  • The ability to work on multiple models in one session for comparisons
  • Python plug-in manager
  • Topo, a tool for flange pair handling and identification
  • Mesh copying to identical geometry
  • New volume mesh algorithm for hexahedral elements
  • Laminate tool visibility improvements
  • Solid laminate support
  • Support sub-modeling tool for ANSYS and Abaqus solves

The μETA post-processor 16.0.0 release focuses on increasing the number of interfaces with solver data. These interfaces include BETA CAE Systems’ standard solver and Eπilysis. The tool has also been optimized for NVH, CFD, durability and crash simulations.

μETA now includes a few new tools to help users perform certain post-processing tasks. For example, the strain gauge tool allows users to add a strain scale to a 3D model and calculate the results. Another tool that users will find useful is the XML comparison tool. This tool allows users to compare two XML files and save a new file based on their differences and settings.

Other key improvements to μETA include:

  • Read and select multiple results
  • Menus altered to improve usability
  • Animation editor
  • Python plug-in manager
  • Template curve creation from NASTRAN and Abaqus
  • Flow path calculations and displays of streaklines and particle rebounds

Since the CAE community helped in the creation of Eπilysis, what improvements to the solver would you like to see? What improvements should be included in ANSA and μETA? Comment below.
