IMPETUS Afea Solver Engine

We’re happy to announce a new version of IMPETUS Afea Solver Engine. This version contains bug fixes, added functionality and improvements.

New engine commands

Petrify

*PETRIFY is used to temporarily or permanently turn deformable parts into rigid bodies.

More accurate contact

*CONTACT_ACCURACY is used to locally increase the accuracy of the contact calculations. The specified levels will overrule lower accuracy levels specified in *CONTACT.

Contact force sensor

*OUTPUT_CONTACT_FORCE acts as a contact force sensor. It samples forces and outputs the data in ASCII format (contact_force.out).

Local material direction

*INITIAL_MATERIAL_DIRECTION_PATH is used to define local material directions in components that are modeled with one single element in thickness direction.

Composite geometry

*GEOMETRY_COMPOSITE combines multiple sub-geometries into one, more complex, geometry.

Engine release notes v6.0.726

  • *INITIAL_MATERIAL_DIRECTION_PATH: A new command to define initial material directions.
  • *GEOMETRY_COMPOSITE: A new command that combines multiple sub-geometries into one, more complex, geometry.
  • *OUTPUT_CONTACT_FORCE: A new command that act as a contact force sensor. It samples forces and outputs the data in ASCII format (contact_force.out).
  • *VULNERABLE_AREA_ASSESSMENT: Improved geometrical accuracy.
  • *PARTICLE_DOMAIN: Speed-up of particle filling process (faster initialization).
  • *CONTACT_ACCURACY: New command for local control of contact accuracy parameters.
  • *INITIAL_VELOCITY: Added support for velocity definition in local coordinate system.
  • *PARTICLE_SPH: Improved treatment of the interaction between different SPH objects.
  • *ELEMENT_REBAR: Added coupling between rebar truss elements and SPH (concrete).
  • *PARTICLE_DETONATION: Added an optional parameter that limits the detonation process to one specific sub-domain ID.
  • *RIGID_BODY_JOINT: Fixed bug related to large joint rotations.
  • *PETRIFY: New command for deformable-to-rigid switching.
  • *GEOMETRY_SEED_COORDINATE: Added part ID option.
  • *REMAP: Improved interpolation scheme.
  • Fixed issue with nested ~if statements.
  • *PARAMETER: Improved unit system conversion capabilities.
  • *REFINE: Improved capabilities for pentahedra elements.
  • *PARTICLE_SPH: Bux fix in interaction between different SPH materials. Default setting was incorrectly “no tension”, which had a negative impact on shaped charge penetration capacity simulations.
  • *GEOMETRY_PART: Bug fix in SPH and discrete particle filling algorithm.
