void MAST::FEMOperatorMatrix::reinit	(	unsigned int	n_interpolated_vars,

	)

inline

this initializes the operator for number of rows and variables, assuming that all variables has the same number of dofs.

This is typically the case for structural strain operator matrices. Note that when this method is used the user must set the matrix entries by calling set_shape_functions

Here is the call graph for this function:

void MAST::FEMOperatorMatrix::reinit	(	unsigned int	n_interpolated_vars,

	)

inline

this initializes all variables to use the same interpolation function.

It is assumed that the number of discrete vars is same as the number of interpolated vars. This is typically the case for fluid elements and for structural element inertial matrix calculations

sets the shape function values for the block corresponding to interpolated_var and discrete_var.

This means that the row interpolated_var, the value in columns discrete_vars*n_discrete_dofs_per_var - (discrete_vars+1)*n_discrete_dofs_per_var-1) will be set equal to shape_func .
