9.6.1. Named Input File Formats

The Named Input File format is used for Batch Files and Report Template Files.

File Format	Description
Batch File Format (bgi)	In most cases, this is the best file format to use for interfacing with BladeGen. BladeGen will write this file format from the File \| Save As... menu command. Right-clicking on a file in the Windows Explorer will display a popup menu with an Edit option to edit the file.
Report Template File Format (bgr)	This file format is created and edited when using the File \| Export \| Report... menu command.

9.6.1.1. Named Input File Guidelines

The Named Input Files use the following guidelines.

The file is read and processed a line at a time, except in the Default and Equation sections (where applicable).
Comments are written on lines that start with an exclamation mark (!) and that precede all other lines of the file. If comment lines appear anywhere other than at the top of the file, an error will occur when the file is processed.
Variables, Keywords, and Parameters enclosed in brackets [] are optional.
Lists of options are enclosed in braces {} and are comma delimited.
All sections start with a line like "{New, Begin} SectionName" and ends with a line like "End SectionName", where SectionName is the name of the section. An example is below.
```
Begin SectionName
    variable1=0
    variable2=1
        Begin SubSectionName
            variable3=2
        End SubSectionName
End SectionName
```
All variables have a default which will be used unless another value is given. There are no defaults for the sections, so all required sections must be defined in order for the file to be complete.

Named Input Parameter Types

9.6.1.2. Named Input Section Types

The Named Input File Format uses Sections to distinguish between groups of parameters or to signal the start of a new object.

Object Type	Description
Generic Object	Generic section header.
Data	Used to enclose a list of point data. Each point is to be on a separate line and follow the rules of the Point Parameter type.
EquSet	Used to enclose a set of equations. Allows the use of multi-line control statements (if...else...endif). One statement per line.

9.6.1.3. Named Input Parameter Types

The Named Input File Format uses specific parameter types. Usually the user doesn’t need to know the details of the variable, but this information is included for completeness.

Parameter Type	Description
Boolean	Logical True or False. Accepts "T", "F", "+", "-", "0", or "1". Assigns value to a variable of type bool.
Bitmask	Logical True or False. Accepts "T", "F", "+", "-", "0", or "1". Assigns value to a single bit of a unsigned 32 bit integer.
Integer	Accepts an integer value with range checking.
Double	Accepts a floating point value with range checking.
Point	Accepts a pair of floating point values, separated by a comma, and enclosed in parentheses.
List	Accepts one of the defined strings as an index. Assigns index to a integer variable.
String	Accepts a string enclosed in quotes.
FileName	Accepts a string enclosed in quotes. This is a derivative of the String type used in the editor to prompt for the string using the File Open or File Save dialog.

9.6.1.4. Named Input Equations

The named input parameters allow equations to be used to define the values.

9.6.1.4.1. Named Input Operators

The following operators are available for use in equations. They are processed from the lowest to highest order.

Operator	Order	Description
!	1	Unary Not
~	1	Unary Complement
-	1	Unary Minus
*	2	Multiplication
/	2	Division
%	2	Modulus
+	3	Plus
-	3	Minus
<<	4	Bit Shift Left
>>	4	Bit Shift Right
<	5	Compare LT
<=	5	Compare LE
>	5	Compare GT
>=	5	Compare GE
==	6	Compare EQ
!=	6	Compare NE
&	7	Bitwise AND
^	8	Bitwise XOR
\|	9	Bitwise OR
&&	10	Logical AND
\|\|	11	Logical OR

9.6.1.4.2. Named Input Functions

The following functions are available for use in equations.

Function Name	Prototype*	Description
defined	b=defined(v)	Variable or Constant exists.
min	pdi=min(pdi,pdi)	Minimum value or length(p).

tan	d=tan(d)	Tangent.
ln	d=ln(d)	Natural Logarithm.
log	d=log(d)	Logarithm (base 10).
pow	d=pow(d,d)	Power.
dist	d=dist(p,p)	Distance between points.
polar	p=polar(d,d)	Vector from radius and angle.
rotate	p=rotate(p,d)	Rotate vector by specified angle.
unitvec	p=unitvec(p)	Normalized vector to unit (1.0) length.
xval	d=xval(p)	X value of point.
yval	d=yval(p)	Y value of point.

* Note: Data types are identified by the character. The table below correlates the character to the data type.

Char	Data Type
b	Boolean
i	Integer
d	Floating
p	Point (Float pair)
v	Any of the above

9.6.1.4.3. Named Input Constants

The following constants are available for use in equations. Their values can not be overwritten.

Constant	Value
Pi	3.141592653589793
e	2.718281828459045
g	32.174[ft/s2]

F	False
true	True
false	False

9.6.1.4.4. Named Input Control Statements

When a multi-line equation is permitted (only in EquSet Sections), the following control statements are allowed.

If...Endif

This control statement allows conditional evaluation of a set of statements, determined by the evaluation of the condition.

if ( condition )
  {expressions}
endif

If...Else...Endif

This control statement allows conditional evaluation of two set of statements, determined by the evaluation of the condition.

if ( condition )
  {true expressions}
else
  {false expressions}
endif

9.6.1.5. Batch Input File Format (BGI)

The following topics are discussed:

9.6.1.5.1. Batch File Format (BGI)

This file format was developed to assist other programs in interfacing with BladeGen. Please see Named Input File Format for a description of the notation used.

BladeGen writes this file and there is a ’BladeBatch.exe’ program which can be used to output geometric values or grids based on input from this file. Operation of the program is detailed in Batch Processing .

The file format supports both a detailed description of the geometry (as output from BladeGen) and a simplified description for easy entry into BladeGen. The following topics show examples of the file format for reference.

Complete BGI File Format Listing

BGI Angle/Thickness Example

BGI Pressure/Suction Example - Prs/Sct Curves

BGI Pressure/Suction Example - Bezier Curves

The file format uses sections which must be defined in the given order. The Default and Equation sections are created as empty sections by BladeGen, but a dialog is provided for user input.

Defaults Section

This section describes the default values of parameters that can be overridden by command line definitions (in BladeBatch).

Equations Section

This section describes the equations for constants that can use the default values or command line definitions (in BladeBatch).

Model Section

This section describes the parameters that apply to the model as a whole.

Meridional Section

This section describes the design meridional definition of the model. The hub and shroud curves must be defined before the leading and trailing edge curves, since these two curves reference the prior two curves for their end points. All of the curves must be defined before creating the layers, since the layers use %span (which is defined by the four curves).

The SimpleMeridionalProfile can be used as an alternative to the definitions for the four curves and the hub and shroud layers (created as spanwise layers at 0.0 and 1.0). These definitions can be mixed, but this should be avoided.

Blade Section

This section describes the blade’s parameters. At least one blade is required, and the first defines the main blade. Additional blades can be added as splitters.

MasterMeridional Section

This section describes the master meridional definition of the model. It is identical to the Meridional section detailed above, but is used for output only (when selected).
