MAGREC Interface



The translator creates a grid and boundary conditions file in the MAGREC file format. MAGREC is a Hitachi in-house code for the computation of magnetic field.

Creating the MAGREC Input File

The translator writes the MAGREC input file using an unstructured domain file and its corresponding boundary conditions file. To create the MAGREC input file, select the translator "MAGREC" in the "Output" menu from the ICEM CFD/CAE Manager. After clicking "Write output" you can specify options for the MAGREC interface: The interface generates the MAGREC file in the Transfer Shell. You may open a shell window in this directory by selecting the menu items "Utility" and "Transfer Shell".

Defining boundary conditions and properties for MAGREC

In MULCAD the boundary conditions and properties are defined using the "Unspec. Bound. Cond." menu. For grids generated with the HEXA-Mesher or the TETRA-Mesher, the boundary conditions and properties are defined in the "general bound. cond." menu of the DDN-Mesher Interface. Please refer to the General Remarks section for more details.


The properties are optionally defined on each domain or 3D family.

    MULCAD      DDN-Mesher 
    ------      ----------
    1.FLAG      1.string1       Enter the word PROP
    2.NR        3.integer       Enter the material ID number (default is 1)
    3.VALUE     4.real1         Enter the IDRC flag, 1<=idrc<=6 (default is 4)
    4.X         5.real2         Enter the x-component of the density vector
    5.Y         6.real3         Enter the y-component of the density vector
    6.Z         7.real4         Enter the z-component of the density vector
    7.SCALE     8.real5         Enter the coefficient of magnetic permeability - Cmu 
                                (default is 1.257e-6)
Boundary types

The boundary types can be defined on subfaces or 2D families.

    MULCAD      DDN-Mesher 
    ------      ----------
    1.FLAG      1.string1       Enter the word TYPE
    2.NR        3.integer       Enter the boundary type no.(0,1 or 2)
The default boundary type is zero for all external walls. Note that when a block with an IDRC of 1, 2 or 3 interfaces with a block with an IDRC of 4, 5 or 6, a boundary is automatically created at the interface between the two blocks with the default boundary type of zero.
