Writing History Records
To write a family of files containing history records:
- Create the file using createb.
- Write all of the non-record (time independent) variables to the file
- Create a record which will correspond to time time and cycle
for future jt and jc commands. Use:
add_record, f, time, ncyc make new record at time,
- Write all record (time dependent) variables to the file using
After the first add_record, save will create and store
record variables instead of non-record variables as in step 2.
- Repeat steps 3 and 4 for each new record you wish to add to the file.
For the second and subsequent records, save will not allow variables
which were not written to the first record, or whose data type or shape
has changed since the first record. That is, the structure of all history
records in a file must be identical. Use type pointer variables
to deal with data which changes in size, shape, or data type.
After each add_record, any number of save commands
may be used to write the record.
If the current member of a history record file family has at least one
record, and if the next record would cause the file to exceed the maximum
allowed file size, add_record will automatically form the next
member of the family. The maximum family member file size defaults to 4
