3.40 DIRHA

3.40 DIRHA

Calling sequence : CALL DIRHA (ANAME, NCOMPS, RTYPE, NUMVAR, IEXIT, IUNT)

Purpose : To enter a result attribute definition.

Parameters :

ANAME	Attribute name (Character*8)
NCOMPS	Number of components (Integer)
RTYPE	Entity type to which components are attributed (Integer) 1 Nodal materially independent 2 Nodal materially dependent 3 Element at nodes 4 Element at Gauss points 5 Element, constant for element
NUMVAR	Number of record variants (Integer)
IUNT	Temporary file channel number (Integer)
	Out
IEXIT	Error condition (Integer)

Use: This routine is called immediately after routine DIHED for all User-defined results data sets. It must be used in conjunction with routine DIRHB and optionally with routine DIRHC to enter the additional sub-headers necessary to define a results data set. This routine is called to define a result attribute. The definition consists of the attribute name, the number of results

components for this attribute, the type of results which are to follow, and the number of record variants.

For complex results, confusion can arise over the number of results components that are to be input. If the user wishes to enter data in the form of 3 complex components, NCOMPS should be set to 3 here, and then routine DIRHC called 3 times. When one then enters the data (for each node using DINIA for example), NUMRES must be set to 6, in this case. The 6 values would be entered in the following order:

r1(real), r1(imag), r2(real), r2(imag), r3(real), r3(imag)

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)
156		Cannot enter results, current dataset is : (KEY )
157		Attribute header already entered
182		Invalid results type (irtype)
183		Invalid number of components (ncomps)
184		Invalid number of attribute variants (numvar)
211		Invalid temporary file unit number (iunt)
