Introduction
A brief description of the example.
*CONTROL_ADAPTIVE Cylinder Undergoing Deformation with Adaptivity LS-DYNA Manual Section: *CONTROL_ADAPTIVE Additional Sections: *DEFINE_COORDINATE_VECTOR Example: Cylinder Undergoing Deformation with Adaptivity Filename: control_adaptive.cylinder.k Description: Several nodes on a cylinder are given initial velocities towards the center of the cylinder causing the cylinder to indent. To improve accuracy, adaptivity is defined so that the mesh of the cylinder is re-fined during the deformation. Model: Only 1/4 of the system is modeled becaus e of symmetry. The boundary conditions on the cylinder are defined with single point constraints (SPC's). Because of the geometry orientation, several of the SPC's require local coordinate system defined using the keyword *DEFINE_COORDINATE_VECTOR. Results: Before and after mesh refinement are shown in the figures. Additionally, the total, kinetic and internal energy from the glstat ascii file are shown. The entire initial kinetic energy is absorbed by the cylinder due to material deformation (internal energy).
