MoFEMErrorCode MetaSpringBC::addSpringElements ( MoFEM::Interface &  m_field,
const std::string  field_name,
const std::string  mesh_nodals_positions = "MESH_NODE_POSITIONS" 
)
static

Declare spring element.

Search cubit sidesets and blocksets with spring bc and declare surface element

Blockset has to have name “SPRING_BC”. The first two attributes of the blockset are spring stiffness value.

Parameters
m_fieldInterface instance
field_nameField name (e.g. SPATIAL_POSITION)
mesh_nodals_positionsName of field on which ho-geometry is defined
Returns
Error code
Examples
elasticity.cpp, mortar_contact_thermal.cpp, simple_contact.cpp, and simple_contact_thermal.cpp.
