Tools to convert, debug and - FEFlow

This program produces powerfunction output. For every data point that occures in the input
trp_file a powerfunction will be created. Therefore for every point runs a loop over all the triplet
files that are defined in the definition_file. If the point finds in such a time data file then a output
line of the format will be generated. T is the time value according to column 1 in the
definition_file. F is a function value that will be computed according the operation_string.
The operation_string defines the function value in the program output. It can define a
computation using the function value from the input trp_file that is represented as the characters
‘FR’ –reference value- in the operation_string. The function value of the current time data triplet
file will be represented as the characters ‘FT’ -time value- in the operation_string. The resulting
value for the program output will be represented as the character ‘F’ in the operation_string.
Example1: Resulting value is the reference value plus the time dependend values: ‘F = FR + FT’
The reference data will be used as offset for the time dependent data.
Example2: Resulting value is the time dependent value shifted and scaled: ‘F = (FT + 0.36) *
1000.0’
The default value of operation_string is ‘F = FT’. So the reference data will not be used and the
time dependent data will be used without any changes.
The -id start_id option defines the first power function ID. The default value is -999. The power
function ID will be increased automatically. The -s snap_distance option defines the radius
around reference points to identify ‘identical’ points in the time dependent triplet files. The default
value is 1.e-6.
Example:
‘trp2pow_acc’
usage: trp2pow_acc [-t start_time] [-id start_id] [-o ‘operation_string’] definition_file trp_file
trp2pow_acc is very similar to trp2pow. The difference consistes of two points:
The time levels in the definition file and the function values defined in the files
trp_file_at_time_xxx will be interpreted as time step lenght and as value change at this
timestep. (In trp2acc these data will treated as absolute time levels and absolute physical
values at the time.)
The initial time comes from the input parameter -t start_time and the initial value comes from
the input trp_file.
The resulting powerfunction data will be computed in the following way:
