output_control set madata
MADATA generates a modal file. This file serves as input to the Adams Modal program. Adams Modal is an auxiliary program marketed and supported by Mechanical Dynamics, Inc.
Format:
output_control set madata |
|---|
model_name = | model_name |
statics = | yes /no |
time = | real_number |
comment = | string |
Example:
output_control set madata & |
|---|
model_name = | model_1 & |
statics = | yes & |
time = | 10 & |
comment = | "Displacement of wheel center 1 wrt ground" |
Description:
Parameter | Value Type | Description |
|---|
model_name | String | Specifies the model to be modified. You use this parameter to identify the existing model to be affected with this command. |
statistics | Yes/No | Specifies that the modal data is to be dumped from the first static equilibrium analysis and writes it to the modal file. |
time | Real Number greater than 0 | Dumps the modal data at up to thirty time steps (r1[,...,r30]) from the next quasi-static equilibrium analysis or from the next dynamic analysis and writes it to the modal file. |
Comment | String | Specifies a comment for request, mrequest, madata, and results entities. |
Extended Definition:
1. You may identify a model by typing its name or by picking it from the screen.
If the model is not visible on the screen, you must type the name. You may also find it convenient to type the name even if the model is displayed. You must separate multiple model names by commas. If the model is visible in one of your views, you may identify it by picking on any of the graphics associated with it.
2. To record modal data for subsequent static equilibrium analyses, you must use an MADATA command/statement with the STATICS argument just before each static equilibrium analysis.
3. The REAL values for the time parameter (r1[,...,r30]) should correspond to the time steps for a quasi-static equilibrium or a dynamic analysis. The values (r1[,...,r30]) must each be greater than zero.
4. The comment can contain up to 80 characters, and can be comprised of letters of the alphabet (a-z, A-Z), numbers (0-9), and underscores. You may also use spaces and special characters (*&^%$#) if you enclose the comment in quotation marks.
Cautions:
1. Adams always outputs VERBOSE information to the message file regardless of the setting of the VERBOSE parameter.
2. The dump facility essentially maps the equations and variables in your system and provides their numeric codes.
Tips:
1. With Adams Modal, you can linearize a mechanical system about any appropriate point of interest and calculate eigenvalues and eigenvectors for that point in time. You can then use this data to analyze the linear system response. The Adams Modal program includes a comprehensive postprocessor for easy graphic examination of the computed data.
