get_conduction_and_capacity_heat()

virtual void b2000::HeatMaterial3D::get_conduction_and_capacity_heat ( Model *  model, const Element *  element, const double  coordinates[3], const b2linalg::Vector< double, b2linalg::Vdense_constref >  nodes_interpolation, const double  element_coordinate[3], const int  layer_id, const double  covariant_base[3][3], const double  temperature, const double  temperature_dot, const double  grad_temperature[3], const double  time, const double  linear, double  heat_conduction[3], double  d_heat_conduction_d_temperature[3], double  d_heat_conduction_d_grad_temperature[6], double &  heat_capacity, double &  d_heat_capacity_d_temperature, double &  d_heat_capacity_d_temperature_dot, GradientContainer *  gradient_container, SolverHints *  solver_hints  )

pure virtual

Return the heat conduction and capacity of the material at a specific location in an element.

Parameters

element	the element at with the heat are calculated.
coordinates	the position of the material point.
nodes_interpolation	the nodes interpolation at the location in the element. This can be used by the material to interpolate some fields defined by value at nodes.
element_coordinate	the element natural coordinate
layer_id	the layer id or 0 if the material as only one layer. Must be in the interval [0, nb_layer -1].
covariant_base	the covariant natural base at the location. This can be used to compute a material referential.
temperature	the temperature (or 0 for a linear analysis).
temperature_dot	the time derivative of the temperature (or 0 for a static analysis).
grad_temperature	the gradient of the temperature field in the global base. grad_temperature[i] = d t / d xi
time	the current time (or 0 for a static analysis).
linear	a flag that must be set to true if the returned heat must be computed linearly.
heat_conduction	the heat flux due to the conduction in the tree direction x0, x1, x2 of the global referential.
d_heat_conduction_d_temperature	the derivative of the heat conduction flux 'heat_conduction' relatively to the temperature 'temperature'.
d_heat_conduction_d_grad_temperature	the derivative of the heat conduction flux 'heat_conduction' relatively to the temperature gradient 'grad_temperature'. The 3x3 symmetric matrix is stored in lower packed format in a array of size 6.

d_heat_conduction_d_grad_temperature[0] = d h0 / d gt0 d_heat_conduction_d_grad_temperature[1] = d h1 / d gt0 d_heat_conduction_d_grad_temperature[2] = d h2 / d gt0 d_heat_conduction_d_grad_temperature[3] = d h1 / d gt1 d_heat_conduction_d_grad_temperature[4] = d h2 / d gt1 d_heat_conduction_d_grad_temperature[5] = d h2 / d gt2

Parameters

heat_capacity	the heat flux due to the capacity
d_heat_capacity_d_temperature	the derivative of the heat capacity flux 'heat_capacity' relatively to the the temperature 'temperature'.
d_heat_capacity_d_temperature_dot	the derivative of the heat capacity flux 'heat_capacity' relatively to the time derivative of the temperature 'temperature_dot'.
gradient_container	the pointer to the gradient container or 0 if the gradient must by not computed.
solver_hints	the pointer to an SolverHints object or 0. Allows to give hints to the iterative solver if to diverge and when to converge.
