Motion

Define direct, derived, and constrained mesh motion.

Attention: The icons shown on the ribbon below are used to complete this workflow. Click an icon to learn more about the tool.
Use the Settings tool to define the mesh motion equation to be solved. Use Translation tool to define linear mesh translation on solid bodies or surfaces. Use Rotation tool to define mesh rotation on solid bodies or surfaces. Use the Rigid Body tool to simulate the dynamic motion of a body under the influence of forces and moments. Use the Interpolated tool to interpolate direct mesh movement onto surrounding solids/surfaces and update the mesh accordingly. Use the Planar Slip tool to constrain surface mesh on planar faces. Mesh on selected surfaces will only be allowed to slip tangentially along the planar surface. Use the Guided tool to constrain/guide nodes along a given surface. Use the Free Surface tool to specify free surfaces and impose the appropriate nodal boundary condition on the mesh motion on those surfaces. Free surface properties are defined by surface tension and contact angle parameters. Use the External Surface tool to specify a fluid surface that interacts with a solid/structural surface from an external code in order to solve Direct Coupling Fluid Structure Interaction (DC-FSI) problems. Use the Interface Surface tool to define an interface for moving mesh. Optionally, this tool allows you to define topological baffle surfaces as an interface surface. Use the Advanced tool to define motion based on the position of two reference points at different times. This is useful when you want to define arbitrary motion with time. Use the No Constraints tool to allow the solver to move surfaces according to surrounding node motion. Use the Advanced Spatial tool to define nodal motion conditions. This is useful to define mesh displacement and/or mesh velocities along with other motion. It can be used to simulate a train moving through tunnel, a car changing lanes, food injection, and so on.
