Mesh Nonlinear Adaptivity (NLAD)

This Tips & Tricks video shows how to use Mesh Nonlinear Adaptivity (NLAD) capabilities in ANSYS Mechanical Workbench.

Nonlinear adaptivity refers to the capability of the solution process to adapt to changing conditions during a nonlinear analysis. The solution process uses a feedback mechanism to discretely or continuously adjust some internal parameters automatically so that an accurate and convergent solution is obtained.

Adaptive meshing is an example of an adaptive process. In highly nonlinear problems, excessive deformation can cause parts to distort and/or fail. Nonlinear mesh adaptivity modifies the mesh automatically based on specified criteria. Mesh modifications occur by splitting and/or morphing or by general remeshing. Loads, boundary conditions, contact conditions, solutions variables, etc., are seamlessly transferred to the new mesh as the solution progresses.
