The restriction function type depends upon the tensor type of field
. The following are the restriction functions
:
Current value:
This function consists of the current value of
. This function can only be applied when
is a scalar field. This is selected automatically, since the values of the scalars are detected.
Norm of vector:
This function computes the norm of the vector
. This function can only be applied when
is a vector field.
component of vector or tensor:
This function extracts the
component of a vector or a tensor.
