Chapter 24: Explicit Dynamics Blast Analysis in Mechanical

An initial prototype exposing the Autodyn blast analysis functionality in the Explicit Dynamics analysis system is available through the EXD Euler Enhancements beta feature flag. To set this flag in Workbench, open the Tools > Options dialog. Check the box next to the option in the Mechanical tab.

The functionality exposed under this beta feature for release 2025 R1 is as follows:

  • Two different domain types for 2D Euler analyses:

    • 1D wedge domain for performing a 1D blast

    • 2D grid domain

  • Exposure of the Detonation Point in 2D

  • Output of data files (with file extension .fil) of the results of a 2D axisymmetric MME analysis to be used for remapping into a 3D MME analysis

  • Remapping from a 2D data file (extension .fil) into a 3D MME analysis in Mechanical exposed via an ACT extension
