3.9 DICON

---

Calling sequence : CALL DICON (IDNNUM, IDOF, IDSNUM, IEDOF, IEXIT, IUNT)



Purpose : To enter a nodal constraint data record



Parameters :

In

IDNNUM	Node identification Number (Integer)
IDOF	Degrees of freedom constrained (Integer) 1 : X Translation 2 : Y Translation 3 : Z Translation 4 : X Rotation 5 : Y Rotation 6 : Z Rotation 9 : All Any integer which is a combination of at most five digits (1-6) is valid
	IDSNUM Local axis system identification Number for degrees of freedom at the node (Integer)
IEDOF	Degrees of freedom made external (Integer) 1 : X Translation 2 : Y Translation 3 : Z Translation 4 : X Rotation 5 : Y Rotation 6 : Z Rotation 9 : All Any integer which is a combination of at most five digits (1-6) is valid
	IUNT Temporary file channel number (Integer)

Out

IEXIT

Error condition (Integer)

Use : This routine is called once for each node attached to a valid FEMVIEW element type to enter constraint information. One constraint is processed at a time.



The data has to be entered in ascending node order.



The local axis system identifier is set either to zero (meaning no local axis system is active) or to an identification number which refers to a local system defined using routine DILXC.



Errors : The error condition is indicated by the value of IEXIT.

IEXIT

Meaning

0			Successful call
32			Current error must be cleared up first
129			Error in writing to temporary file on unit (iunt)
141			Id numbers cannot be less than 1
143			Id above 99999 not allowed for 5 digit character file
169			Id numbers not in ascending order
176			Idof and iedof cannot both be zero
194			Cannot enter this data type, current dataset is : (KEY )
196			Invalid nodal constraint definition (idof)
197			Invalid nodal constraint definition (iedof)
211			Invalid temporary file unit number (iunt)
