*OUTPUTS

Previous pageNext page

Purpose

To specify the AeroDyn output settings.

Theory

Refer to AeroDyn Overview for further information.

Keyword Format

A block of 3 lines of data, defining the required output nodes as follows:

SUMPRINT=Summary Print

NBLOUTS=Number of Blade Output Nodes, BLOUTND=Blade Out Node 1, ..., Blade Out Node N

NTWOUTS=Number of Tower Output Nodes, TWOUTND=Tower Out Node 1, ..., Tower Out Node N

 

This is then followed by a block of 2 lines of data requesting the relevant outputs, which may be repeated as often as required:

COMMENT=Comment Line

OUTLIST=Output List

 

Set Summary Print to 1 to generate a summary file with name OutFileRoot.AD.sum. OutFileRoot is specified in the I/O SETTINGS section of the driver input file.

Number of Blade Output Nodes specifies the number of blade nodes for which output is requested. Valid inputs range between 0 and 9. Blade Out Node is a list (which is Number of Blade Output Nodes long) of node numbers between 1 and Number Blade Nodes (corresponding to a row number in the blade analysis node table in the blade data input files), separated by any combination of commas, semicolons, spaces, and/or tabs. All blades have the same output node numbers.

Number of Tower Output Nodes specifies the number of tower nodes for which output is requested. Valid inputs range between 0 and 9. Tower Out Node  is a list (which is Number of Tower Output Nodes long) of node numbers between 1 and Number Tower Nodes (corresponding to a row number in the tower analysis node table), separated by any combination of commas, semicolons, spaces, and/or tabs.

The outputs specified in the Output List section determine which quantities are actually output at these nodes. Enter one or more lines containing comma separated output parameter names. The parameters are written in the order they are listed in the input file. You can use multiple lines so that you can break your list into meaningful groups and so the lines can be shorter. You may enter comments to be appended to the Output List line using the COMMENT=Comment Line specifier. Blade and tower node-related quantities are generated for the requested nodes identified through the Blade Out Node and Tower Out Node lists above. If you wish to post-process AeroDyn output parameters using the Flexcom *TIMETRACE, TYPE=AERODYN definition then the output parameters must be requested from the AeroDyn module so they are present in the AeroDyn output file prior to Flexcom post-processing request.

Table Input

Output Information

Input:

Description

Summary Print:

This option allows you to instruct AeroDyn to generate a summary file with name OutFileRoot.AD.sum.

Number of Blade Output Nodes:

The number of blade nodes for which output is requested. Valid inputs range between 0 and 9.

List of Blade Output Node Numbers:

A list (which is Number of Blade Output Nodes long) of node numbers between 1 and Number of Blade Nodes (corresponding to a row number in the blade analysis node table in the blade data input files, which are created by *BLADE GEOMETRY), separated by any combination of commas, semicolons, spaces, and/or tabs. All blades have the same output node numbers.

Number of Tower Output Nodes:

The number of tower nodes for which output is requested. Valid inputs range between 0 and 9.

List of Tower Output Node Numbers:

A list (which is Number of Tower Output Nodes long) of node numbers between 1 and Number of Tower Nodes (corresponding to a row number in the tower analysis node table), separated by any combination of commas, semicolons, spaces, and/or tabs.

Output Channels

Input:

Description

List of Output Parameters:

A list of output quantities to be generated by AeroDyn. Enter one or more rows containing quoted strings that in turn contain one or more output parameter names. Separate output parameter names by commas. If you prefix a parameter name with a minus sign, “-”, underscore, “_”, or the characters “m” or “M”, AeroDyn will multiply the value for that channel by -1 before writing the data. The parameters are written in the order in which they are listed here. Use multiple rows so that you can break your list into meaningful groups and so the rows can be shorter. Blade and tower node-related quantities are generated for the requested nodes identified through the List of Blade Output Node Numbers and the List of Tower Output Node Numbers. If the software encounters an unknown/invalid channel name, it will issue a warning and remove the suspect channel from the output file. Please refer to AeroDyn Output Parameters for a complete list of possible output parameters.

Comments:

You may enter comments relating to each output or group of similar output. These comments are included in the AeroDyn input file for information purposes only.
