Extension of the previous method. Return possible values from the enum FieldResult, see description there. The initial state is field_none, if the field is correctly set on all regions of the region_set given as parameter we return state field_other or even more particular result.

Special field values spatially constant. Could allow optimization of tensor multiplication and tensor or vector addition. field_result_ should be set in constructor and in set_time method of particular Field implementation. We return value result_none, if the field is not initialized on the region of the given element accessor elm. Other possible results are: result_zeros, result_eye, result_ones, result_constant, result_other see FieldResult for explanation.

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:

◆ is_constant()

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 can call ElementAccessor<spacedim>(mesh(), reg ) to construct an ElementAccessor elm pointing to "virtual" element on which Field::value returns constant value. Unlike the Field<>::field_result method, this one provides no value, so it have common header (arguments, return type) and could be part of FieldCommon and FieldSet which is useful in some applications.

TODO: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.

Return true if the value of the field was changed on some region. The returned value is also stored in changed_during_set_time data member.

Default values helps when creating steady field. Note that default TimeGovernor constructor set time to 0.0.

Different field copies can be set to different times.

TODO: update following: Set side of limit when calling set_time with jump time, i.e. time where the field change implementation on some region.

◆ units() [2/2]

FieldCommon& FieldCommon::units ( const UnitSI units)
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.
