Number_of_Nodes : Number of grid nodes.
Number_of_Scalar_Functions : Number of scalar functions.
Number_of_Vector_Functions : Number of vector functions.
Number_of_Matrix_Functions : Number of matrix functions.
Number_of_Metric_Functions : Number of metric functions.
Function_Label : Function label.
The 4-coefficients of the matrix are Mat_0, Mat_1, Mat_2, Mat_3.
They are ordered as shown below.
Mat_0 Mat_1
Matrix = Mat_2 Mat_3
Mat_0 : coefficient 0 of matrix.
Mat_1 : coefficient 1 of matrix.
Mat_2 : coefficient 2 of matrix.
Mat_3 : coefficient 3 of matrix.
The 3-coefficients of the symmetric metric are Met_0, Met_1, Met_2.
They are ordered as shown below.
Met_0 Met_1
Metric = Met_1 Met_2
Met_0 : coefficient 0 of symmetric metric.
Met_1 : coefficient 1 of symmetric metric.
Met_2 : coefficient 2 of symmetric metric.
In the above description, the brackets [ ... ] enclose items in a loop, and braces { ... } enclose items in a single logical record.
In C or C++ Function Label must be declared as "char Function_Label[21]". For example,
char Function_Label[21]; strcpy (Function_Label, 'label_for_function');
Do not use more than 20 characters plus the terminating \0 per function label. In Fortran, Function_Label must be declared as "character*21 Function_Label". For example,
character*21 Function_Label Function_Label = 'label_for_function '
In Fortran, do not use more than 20 characters of text per label. The last location (location 21 out of 21) must be blank.
In FORTRAN unformatted form, the data must be written out or read in using the record format defined above. The floating point data items must all be either real*4 or real*8 data.
In C binary form, the data may be written out or read in using records the length of loops or of the individual data items. The floating point data items must all be either float or double data.
In ASCII formatted form, the data may be written out or read in using records the length of loops or of the individual data items. Data items may be written out in free format of any specific form.
