IV-3. initial_magnetization.dat File#

A fixed-file-format file used for per-element magnetization input ( READ_OPTION(17.7.2) ) of MAGNET(17.7).

Prepare an initial_magnetization.dat file in addition to the input file.

For JSON format, you can use the file name specified by INITIAL_MAGNETIZATION_FILE_NAME(17.7.2).

The magnetization-vector magnitude and magnetization ratio are output items for MAGNETIZATION(10.3) =4, but are not used for magnetization input.

Setting Items#

Detailed Description#

TIME#

TIME(IV-3)#

Dummy time. Even when data for multiple times are present, only the first time data are used.

Because this file sets initial magnetization, only the first data are used.

Type:: Real number (E)
Description:: Time (s)

No Prop.No Mx(T) My(T) Mz(T) |M|(T) Rate#

データタイトル(IV-3)#

Title string for text display. It is not used in the analysis.

Enter the line-3 data for the number of sets specified by NO_DATA of MAGNET(17.7), which equals the number of array elements in JSON format.

No#

No(IV-3)#

Type:: Integer (I)
Description:: Element ID

Prop.No#

Prop.No(IV-3)#

Type:: Integer (I)
Description:: Element material-property ID

Mx(T) My(T) Mz(T) |M|(T) Rate#

Mx(T) My(T) Mz(T) |M|(T) Rate(IV-3)#

Type:

Real number (E)

Mx(T): magnetization in the X (R) direction (T)
My(T): magnetization in the Y (θ) direction (T)
Mz(T): magnetization in the Z direction (T)
|M|(T): magnetization-vector magnitude (optional)
Rate: magnetization ratio (optional)

Note

<Input example> Lines 1 and 2 of the initial_magnetization.dat file are comment lines.

Starting on line 3, enter the line-3 data for the NO_DATA count of MAGNET(17.7), which equals the number of array elements in JSON format.
