Context: Eulerian mesh motion is calculated based on a rectangular bounding box that is constructed by Abaqus. The bounding box cannot be visualized in Abaqus/CAE, but it typically corresponds relatively closely to the Eulerian mesh. The creation and behavior of the bounding box is described in Eulerian mesh motion. You can set restraints and restrictions on the contraction, expansion, and translation of this bounding box as part of the mesh motion boundary condition definition. These restrictions may prevent the Eulerian mesh from completely encompassing the specified object to follow at all times during the analysis. Eulerian mesh motion boundary conditions can be applied only to parts with an Eulerian section assignment, and they cannot be applied in the initial step of an analysis. |
