addSimpleRodElements()

MoFEMErrorCode MetaSimpleRodElement::addSimpleRodElements ( MoFEM::Interface &  m_field, const std::string  field_name, const std::string  mesh_nodals_positions = "MESH_NODE_POSITIONS"  )

static

Declare SimpleRod element.

Search cubit sidesets and blockset ROD and declare volume element

Blockset has to have name "ROD". The first attribute of the blockset is Young's modulus.

Parameters

m_field	Interface insurance
field_name	Field name (e.g. SPATIAL_POSITION)
mesh_nodals_positions	Name of field on which ho-geometry is defined

Returns

Error code

Examples

elasticity.cpp.

fe_simple_rod_rhs_ptr	Pointer to the FE instance for RHS
field_name	Field name (e.g. SPATIAL_POSITION)
mesh_nodals_positions	Name of field on which ho-geometry is defined

Returns

Error code
