java.io.IOException

Method Detail

close

public void close()

setShellThickness

public void setShellThickness(double thickness)

Sets the default thickness value to be used for shell and membrane elements, when it cannot otherwise be inferred from the input.

Parameters:

thickness - default shell/membrane thickness

getShellThickness

public double getShellThickness()

Queries the default thickness value for shell and membrane elements.

Returns:

default shell/membrane thickness

setShellType

public void setShellType(FemReaderWriterBase.ShellType type)

Sets the default type to use for shell elements when this can not be inferred from the input. The default value is ShellType#SHELL.

Parameters:

type - default shell type

getShellType

public FemReaderWriterBase.ShellType getShellType()

Queries the default type to use for shell elements when this can not be inferred from the input.

Returns:

default shell type

setNumbering

public void setNumbering(FemReaderBase.Numbering numbering)

Sets how nodes and elements are numbered based on the input. The default value is FemReaderBase.Numbering.RESET.

Parameters:

numbering - controls how components are numbered

getNumbering

public FemReaderBase.Numbering getNumbering()

Queries how nodes and elements are numbered based on the input.

Returns:

how components are numbered

setCheckOrientation

public void setCheckOrientation(boolean enable)

Sets whether or not element orientation should be checked, and if possible fixed. Peforming the check requires computing or estimating the volume of each element. The default value is true.

Parameters:

enable - if true, enables orientation checking

getCheckOrientation

public boolean getCheckOrientation()

Queries whether element orientations are checked and fixed.

Returns:

true if orientation checking is enabled

setSuppressWarnings

public void setSuppressWarnings(boolean enable)

Sets whether or not warning messages are suppressed.

Parameters:

enable - if true, suppresses warnings

getSuppressWarnings

public boolean getSuppressWarnings()

Queries whether or not warning messages are suppressed.

Returns:

true if warnings are suppressed

getScaling

public Vector3d getScaling()

Queries the x-y-z scale factors which are applied to nodal coordinates.

Returns:

scale factors

setScaling

public void setScaling(Vector3d scaling)

Sets the x-y-z scale factors which are applied to nodal coordinates. Default value is (1,1,1).

Parameters:

scaling - nee scale factors
