list_info eigen_values
List information about all the eigen solution's predicted eigenvalues. You may instruct Adams View to print this information to the "Info Window" or to a file or both.
Format:
list_info eigen_values |
|---|
eigen_solution_name = | an existing eigen |
brief = | on/off |
write_to_terminal = | on/off |
file_name = | string specifying the file path |
Example:
list_info eigen_values & |
|---|
eigen_solution_name = | eigen_1 & |
brief = | on & |
write_to_terminal = | off & |
file_name = | "C:\info.txt" |
Description:
Parameter | Value Type | Description |
|---|
eigen_solution_name | AN EXISTING EIGEN | Specifies an existing eigen_solution. |
brief | ON_OFF | Specifies whether to use the brief form (default) or an extended form of the requested information to be displayed. |
write_to_terminal | ON_OFF | Specify if the information requested is to be sent to the informational window or not. |
file_name | STRING | Specify that the information requested is to be sent to a file with the name specified with the parameter. |
Extended Definition:
1. The information includes:
♦MODE_NUMBER -the sequential number of the mode that was predicted by the eigen solution.
♦FREQUENCY -the natural frequency corresponding to the mode (that is, the eigenvalue)
♦DAMPING -the damping ratio for the mode (the log decrement is another way to represent this quantity).
♦EIGENVALUES -list the real and imaginary part of the eigenvalue.
2. You may identify a eigen_solution by typing its name. Specifies an EIGEN_SOLUTION in a existing analysis. If an eigen_solution is available by default, you may identify it by entering its name only. The EIGEN_SOLUTION must be in an existing analysis that is associated to an existing model. Therefore, any reference to the EIGEN_SOLUTION can include the model and analysis name. For example, assume you have read a result file called "SECOND_GEAR.RES", and this result file contains the analysis "SECOND_GEAR". If you wish to refer to the EIGEN_SOLUTION named "EIG1" for the model "TRANSMISSION", enter .TRANSMISSION.SECOND_GEAR.EIG1 (the .TRANSMISSION.SECOND_GEAR. may be omitted if SECOND_GEAR is the current default analysis_name). SECOND_GEAR refers to the analysis name that the result set came from (or is stored under). The eigen_solution name begins with the letters EIG and ends with the eigen_solution ID number. You must separate multiple eigen_solution names by commas. If the eigen_solution is visible in one of your views, you may identify it by picking on any of the graphics associated with it.
3. The ‘write_to_terminal’ parameter is most likely be used in conjunction with the FILE_NAME parameter to get the information put to a file only.
Tips:
1. If you type a "?", Adams View will list the eigen_solutions available by default.
