Here is the caller graph for this function:

FieldCommon& FieldCommon::input_default ( const string & input_default )

inline

Set default value for the field's key from which the default constant valued field will be constructed.

During the first call of the set_time method, we check that the field is defined on all regions. On regions where it is not set yet, we use given dflt string to get particular instance of FieldBase<> (see check_initialized_region_fields_). The default string is interpreted in the same way as if it appears in the input file as the value of the field. In particular it can be whole record with TYPE of the field etc. Most common choice is however mere constant.

Here is the caller graph for this function:

virtual bool FieldCommon::is_constant ( Region reg )

pure virtual

If the field on given region reg exists and is of type FieldConstant<...> the method method returns true otherwise it returns false. Then one call ElementAccessor<spacedim>(mesh(), reg ) to construct an ElementAccessor elm pointing to "virtual" element on which Field::value returns constant value.

Current implementation use virtual functions and can be prohibitively slow if called for every element. If this becomes necessary it is possible to incorporate such test into set_time method and in this method just return precomputed result.

Set name of the field. In fact there are two attributes set by this method.

The first is name used to identify the field as part of a FieldSet or MultiField objects. This name is permanent and can be set only by this method. Can be accessed by name() method. This name is also used at output.

The second is input_name_ that determines appropriate key name in the input field descriptor. This name is also set by this method, but is stored in the internal shared space which is overwritten during call of copy_from method or assignment operator. Can be accessed by input_name() mathod.

Set the data list from which field will read its input. It is list of "field descriptors". When reading from the input list we consider only field descriptors containing key of named by the field name. These field descriptors has to have times forming ascending sequence.

The list is used by set_time method to set field on individual regions to actual FieldBase descendants.

inline

Set basic units of the field.

Currently, we use it only during output and we represents units just by a string.

TODO: Particular class for representing and conversion of various units would be more appropriate. This can allow specification of the units on the inptu, automatic conversion and the same on the output. Possibly this allow using Boost::Units library, however, it seems to introduce lot of boilerplate code. But can increase correctness of the calculations.
