Field Detail

TETRAHEDRALIZE_HEXES

public static int TETRAHEDRALIZE_HEXES

Tells the reader to subdivide each hexahedral element into five tetrahedra.

ONE_BASED_NUMBERING

public static int ONE_BASED_NUMBERING

Tells the reader to number the nodes and elements starting from one. This is the same convention as used by ANSYS.

Constructor Detail

Method Detail

readFem

public FemModel3d readFem(FemModel3d fem)
                   throws java.io.IOException

Specified by:

readFem in interface FemReader

Throws:

java.io.IOException

read

public static FemModel3d read(FemModel3d model,
                              java.lang.String nodeFileName,
                              java.lang.String elemFileName)
                       throws java.io.IOException

Creates an FemModel with uniform density based on ANSYS data contained in a specified file. The node coordinate data can be scaled non-uniformly using an optional parameter giving scale values about the x, y, and z axes.

Parameters:

model - FEM model to be populated by ANSYS data. If null, a new model is created

nodeFileName - path name of the ANSYS node file

elemFileName - path name of the ANSYS element file

Returns:

created model

Throws:

java.io.IOException - if this is a problem reading the file

read

public static FemModel3d read(FemModel3d model,
                              java.lang.String nodeFileName,
                              java.lang.String elemFileName,
                              double density,
                              Vector3d scale,
                              int options)
                       throws java.io.IOException

Creates an FemModel with uniform density based on ANSYS data contained in a specified file. The node coordinate data can be scaled non-uniformly using an optional parameter giving scale values about the x, y, and z axes.

Parameters:

model - FEM model to be populated by ANSYS data. If null, a new model is created

nodeFileName - path name of the ANSYS node file

elemFileName - path name of the ANSYS element file

density - density of the model

scale - if non-null, gives scaling about the x, y, and z axes

options - option flags. Should be an or-ed combination of TETRAHEDRALIZE_HEXES and ONE_BASED_NUMBERING.

Returns:

created model

Throws:

java.io.IOException - if this is a problem reading the file
