This section is used to describe some of the functions used to govern some of the preferences used with finite element model elements.

pref_fem_get	(minimum_angle)

Description:
This function gets the finite element model minimum angle value from the database.
Input:
Output:
REAL	mininimum_angle	The value returns the mesh/edges snap angle in degrees. This angle controls the automatic snapping of nodes to geometry edge slope discontinuities during seeding, meshing and sweeping operations. These operations will place nodes at all edge slope discontinuities greater than the angle returned by this value.
INTEGER	<Return Value>	This function returns a value of 0 when executed successfully and a non zero value to indicate a change in status or an error.
Error Conditions:
None.

Description:

This function gets the finite element model minimum angle value from the database.

Input:

Output:

REAL

mininimum_angle

The value returns the mesh/edges snap angle in degrees. This angle controls the automatic snapping of nodes to geometry edge slope discontinuities during seeding, meshing and sweeping operations. These operations will place nodes at all edge slope discontinuities greater than the angle returned by this value.

INTEGER

This function returns a value of 0 when executed successfully and a non zero value to indicate a change in status or an error.

Error Conditions:

None.

This function is used in the implementation of the form displayed when the “Finite Element...” selection is picked from the “Preferences” pull down menu.

Please see pref_fem_get.

pref_fem_set	(minimum_angle)

Description:
This function sets the finite element model minimum angle value in the database.
Input:
REAL	mininimum_angle	The value specifies the mesh/edges snap angle in degrees. This angle controls the automatic snapping of nodes to geometry edge slope discontinuities during seeding, meshing and sweeping operations. These operations will place nodes at all edge slope discontinuities greater than the angle specified by this value.
Output:
INTEGER	<Return Value>	This function returns a value of 0 when executed successfully and a non zero value to indicate a change in status or an error.
Error Conditions:
None.

Output:

INTEGER

This function returns a value of 0 when executed successfully and a non zero value to indicate a change in status or an error.

Error Conditions:

None.

If changing the input value minimum_angle changes the number of locations requiring nodes on any edge with a mesh seed, a popup form will be used to request permission to adjust the seed locations on that edge unless the number of locations requiring nodes changes to zero. If the number of locations requiring nodes changes to zero, the existing seeds will not be modified.

This function is used in the implementation of the form displayed when the “Finite Element...” selection is picked from the “Preferences” pull down menu.
