DADiSP / UFF 4.1
Univeral File Format
The Universal File Format (UFF) was originally developed by the
Structural Dynamics Research Corporation (SDRC) in the late 1960s
and early 1970s to facilitate data transfer between computer aided
design (CAD) and computer aided test (CAT) in order to facilitate
computer aided engineering (CAE).
A UFF file consists of multiple formats where each format is
specified as 80 character (FORTRAN card image) ASCII records of
space delimited fields that occur in a specific order according to
each UFF format.
Multiple sets of data can be stored within a single UFF file. The
start of each set of data is indicated by a "-1", right justified,
in columns 1-6. The next line indicates the Universal Dataset
Number/Type. Each type has a different format of header
information and data provided. The end of each set of data is
indicated by a "-1", right justified in columns 1-6.
UFF Type 58
The most commonly used format is UFF Type 58 or "Function at Nodal
DOF". UFF Type 58 is specifically designed for dynamic test data
and is fully supported by DADiSP/UFF. DADiSP/UFF also supports the
binary UFF Type 58b format that allows data to be stored in a more
efficient binary form.
DADiSP/UFF directly imports UFF Type 58 or Type 58b data files and automatically
sets sample rate, offset and engineering
unit information for each channel. Multiple data runs are saved in
separate DADiSP datasets. The imported channels can be loaded into
separate Windows or combined into a single Window for display.
UFF Export Series
DADiSP/UFF allows one or more DADiSP series to be saved to ASCII Type 58 or
Binary Type 58b formats. New series can be appended to existing UFF files.
UFF Data Formats
Type 58 or Type 58b regularly sampled and XY data can be imported or exported. Both real or complex
data values are supported in single or double precision UFF format.
Simple Menu Interface
DADiSP/UFF runs from the DADiSP worksheet and is accessed
by a press of a button. The UFF user interface optionally displays
important file information and automatically formats UFF channel
names into appropriate DADiSP series names.
Full Analysis System
DADiSP provides a complete analysis, display, and processing
environment using UFF data. The integration of
DADiSP/UFF into DADiSP makes it easy to automate data import
and analysis applications through SPL (Series Processing
Language), macros, and command files.
DADiSP/UFF requires DADiSP 6.5 B05
for information about updating your current
version of DADiSP.
