Radioss proposes different formats for time history files (T-file ‘RunnaleTnn’); default one is binary (IEEE 32-bit). The article below describes how to specify ASCII format and how to define it for a separate time history file. Generating different time history file can also be useful to separate specific results from standard outputs (e.g. output forces of all the connectors of a given vehicle).
Formats for Time History files is defined using Type parameter.
If you want to specify ASCII (text) format then select Type = 3 (corresponding to /TFILE/3 in Engine file).
That way all TH outputs will be written in the T01 file, in ASCII format.
NB ASCII output formats (types 2 and 3) are not documented; Altair recommends to use binary default format.
As mentioned above, if one is using Type = 3 in TFILE command, then all TH outputs will be written in ASCII format (including global TH outputs).
So, one may want alternately to write only a selection of TH outputs in ASCII format, let say a nodal output and an interface output.
In this case, following setting can be used
Like that, one will get
More generally, one can define additional time history files named RunnameTnnx (with x= A to I). Their contents is defined through the option /xTH (where x= A to I). The frequency and the type of output for the additional time history files are defined using /xTHFILE (where x = A to I).
