Record 2: Format(80A1) Field 1 - ID Line 2 Record 3: Format(80A1) Field 1 - ID Line 3 NOTE ID Line 3 is generally used to identify when the function was created. The date is in the form DD-MMM-YY, and the time is in the form HH:MM:SS, with a general Format(9A1,1X,8A1). Record 4: Format(80A1) Field 1 - ID Line 4 Record 5: Format(80A1) Field 1 - ID Line 5 Record 6: Format(2(I5,I10),2(1X,10A1,I10,I4)) DOF Identification Field 1 - Function Type 0 - General or Unknown 1 - Time Response 2 - Auto Spectrum 3 - Cross Spectrum 4 - Frequency Response Function 5 - Transmissibility 6 - Coherence 7 - Auto Correlation 8 - Cross Correlation 9 - Power Spectral Density (PSD) 10 - Energy Spectral Density (ESD) 11 - Probability Density Function 12 - Spectrum 13 - Cumulative Frequency Distribution 14 - Peaks Valley 15 - Stress/Cycles 16 - Strain/Cycles 17 - Orbit 18 - Mode Indicator Function 19 - Force Pattern 20 - Partial Power 21 - Partial Coherence 22 - Eigenvalue 23 - Eigenvector 24 - Shock Response Spectrum 25 - Finite Impulse Response Filter 26 - Multiple Coherence 27 - Order Function 28 - Phase Compensation Field 2 - Function Identification Number Field 3 - Version Number, or sequence number Field 4 - Load Case Identification Number 0 - Single Point Excitation Field 5 - Response Entity Name ("NONE" if unused) Field 6 - Response Node Field 7 - Response Direction 0 - Scalar 1 - +X Translation 4 - +X Rotation -1 - -X Translation -4 - -X Rotation 2 - +Y Translation 5 - +Y Rotation -2 - -Y Translation -5 - -Y Rotation 3 - +Z Translation 6 - +Z Rotation -3 - -Z Translation -6 - -Z Rotation Field 8 - Reference Entity Name ("NONE" if unused) Field 9 - Reference Node Field 10 - Reference Direction (same as field 7) NOTE Fields 8, 9, and 10 are only relevant if field 4 is zero. Record 7: Format(3I10,3E13.5) Data Form Field 1 - Ordinate Data Type 2 - real, single precision 4 - real, double precision 5 - complex, single precision 6 - complex, double precision Field 2 - Number of data pairs for uneven abscissa spacing, or number of data values for even abscissa spacing Field 3 - Abscissa Spacing 0 - uneven 1 - even (no abscissa values stored) Field 4 - Abscissa minimum (0.0 if spacing uneven) Field 5 - Abscissa increment (0.0 if spacing uneven) Field 6 - Z-axis value (0.0 if unused) Record 8: Format(I10,3I5,2(1X,20A1)) Abscissa Data Characteristics Field 1 - Specific Data Type 0 - unknown 1 - general 2 - stress 3 - strain 5 - temperature 6 - heat flux 8 - displacement 9 - reaction force 11 - velocity 12 - acceleration 13 - excitation force 15 - pressure 16 - mass 17 - time 18 - frequency 19 - rpm 20 - order 21 - sound pressure 22 - sound intensity 23 - sound power Field 2 - Length units exponent Field 3 - Force units exponent Field 4 - Temperature units exponent NOTE Fields 2, 3 and 4 are relevant only if the Specific Data Type is General, or in the case of ordinates, the response/reference direction is a scalar, or the functions are being used for nonlinear connectors in System Dynamics Analysis. See Addendum 'A' for the units exponent table. Field 5 - Axis label ("NONE" if not used) Field 6 - Axis units label ("NONE" if not used) NOTE If fields 5 and 6 are supplied, they take precendence over program generated labels and units. Record 9: Format(I10,3I5,2(1X,20A1)) Ordinate (or ordinate numerator) Data Characteristics Record 10: Format(I10,3I5,2(1X,20A1)) Ordinate Denominator Data Characteristics Record 11: Format(I10,3I5,2(1X,20A1)) Z-axis Data Characteristics NOTE Records 9, 10, and 11 are always included and have fields the same as record 8. If records 10 and 11 are not used, set field 1 to zero. Record 12: Data Values Ordinate Abscissa Case Type Precision Spacing Format ------------------------------------------------------------- 1 real single even 6E13.5 2 real single uneven 6E13.5 3 complex single even 6E13.5 4 complex single uneven 6E13.5 5 real double even 4E20.12 6 real double uneven 2(E13.5,E20.12) 7 complex double even 4E20.12 8 complex double uneven E13.5,2E20.12 -------------------------------------------------------------- NOTE See Addendum 'B' for typical FORTRAN READ/WRITE statements for each case. General Notes: 1. ID lines may not be blank. If no information is required, the word "NONE" must appear in columns 1 through 4. 2. ID line 1 appears on plots in Finite Element Modeling and is used as the function description in System Dynamics Analysis. 3. Dataloaders use the following ID line conventions ID Line 1 - Model Identification ID Line 2 - Run Identification ID Line 3 - Run Date and Time ID Line 4 - Load Case Name 4. Coordinates codes from MODAL-PLUS and MODALX are decoded into node and direction. 5. Entity names used in System Dynamics Analysis prior to I-DEAS Level 5 have a 4 character maximum. Beginning with Level 5, entity names will be ignored if this dataset is preceded by dataset 259. If no dataset 259 precedes this dataset, then the entity name will be assumed to exist in model bin number 1. 6. Record 10 is ignored by System Dynamics Analysis unless load case = 0. Record 11 is always ignored by System Dynamics Analysis. 7. In record 6, if the response or reference names are "NONE" and are not overridden by a dataset 259, but the correspond- ing node is non-zero, System Dynamics Analysis adds the node and direction to the function description if space is sufficie 8. ID line 1 appears on XY plots in Test Data Analysis along with ID line 5 if it is defined. If defined, the axis units labels also appear on the XY plot instead of the normal labeling based on the data type of the function. 9. For functions used with nonlinear connectors in System Dynamics Analysis, the following requirements must be adhered to: a) Record 6: For a displacement-dependent function, the function type must be 0; for a frequency-dependent function, it must be 4. In either case, the load case identification number must be 0. b) Record 8: For a displacement-dependent function, the specific data type must be 8 and the length units exponent must be 0 or 1; for a frequency-dependent function, the specific data type must be 18 and the length units exponent must be 0. In either case, the other units exponents must be 0. c) Record 9: The specific data type must be 13. The temperature units exponent must be 0. For an ordinate numerator of force, the length and force units exponents must be 0 and 1, respectively. For an ordinate numerator of moment, the length and force units exponents must be 1 and 1, respectively. d) Record 10: The specific data type must be 8 for stiffness and hysteretic damping; it must be 11 for viscous damping. For an ordinate denominator of translational displacement, the length units exponent must be 1; for a rotational displacement, it must be 0. The other units exponents must be 0. e) Dataset 217 must precede each function in order to define the function's usage (i.e. stiffness, viscous damping, hysteretic damping). Addendum A In order to correctly perform units conversion, length, force, and temperature exponents must be supplied for a specific data type of General; that is, Record 8 Field 1 = 1. For example, if the function has the physical dimensionality of Energy (Force * Length), then the required exponents would be as follows: Length = 1 Force = 1 Energy = L * F Temperature = 0 Units exponents for the remaining specific data types should not be supplied. The following exponents will automatically be used.

Addendum B There are 8 distinct combinations of parameters which affect the details of READ/WRITE operations. The parameters involved are Ordinate Data Type, Ordinate Data Precision, and Abscissa Spacing. Each combination is documented in the examples below. In all cases, the number of data values (for even abscissa spacing) or data pairs (for uneven abscissa spacing) is NVAL. The abcissa is always real single precision. Complex double precision is handled by two real double precision variables (real part followed by imaginary part) because most systems do not directly support complex double precision.
