Overview
?Mesh is fixed in space, material flows through cell faces
?Normally used for modelling of fluids, gases and large deformation of solids
?Multiple material Solver with strength
–Uses Godunov method
–Material transported from cell to cell
–Algorithms determine the state of cells containing multiple materials
–General mesh in 2D, rectilinear mesh in 3D
?In-flow and Out-flow boundaries
?Joined Parts
?Coupling to Lagrange solvers
Euler Computation Cycle
Filling Euler Parts with Material (2D)
?Lagrange Parts can be created and used to “fill” regions of an Euler Part with materials and initial conditions (e.g. initial velocity)
–Structured Lagrange Parts created in AUTODYN
–Unstructured Lagrange Parts created in Workbench
?Lagrange Parts that are only used to “fill” Euler Parts should be deleted prior to Solving
Filling Euler Parts with Material (3D)
?Lagrange or Fill Parts can be created and used to “fill” regions of an Euler Part with materials and initial conditions (e.g. initial velocity)
–Structured Lagrange or Fill Parts created in AUTODYN
–Unstructured Lagrange Parts created in Workbench
?Lagrange Parts that are only used to “fill” Euler Parts should be deleted prior to Solving
?Fill Parts need not be deleted (they are not computed or visualized)
Example: Hypervelocity Jet Penetration (2D Axial)
Example: Bullet Penetration of Mild Steel (2D Axial)
Example: Detonation in a Rigid Cylinder (2D Axial)
