How to Make Boundary Conditions Conditional in Your Simulation

WebbIn ABAQUS/Standard you can prescribe jumps in displacements. For example, a displacement-type boundary condition is used to apply a prescribed displacement magnitude of 0.5 in degree of freedom 1 to the nodes in node set EDGE.In a second step these nodes can be moved by another 0.5 length units (to a total displacement of 1.0) by … WebbThe Neumann boundary condition guarantees that the simulation domain is self-contained and there are no fluxes across the boundary.

Webb4 juli 2024 · A boundary condition expresses the behavior of a function on the boundary (border) of its area of definition. An initial condition is like a boundary condition, but then for the time-direction. Not all boundary conditions allow for solutions, but usually the physics suggests what makes sense.
