3.25 DIHED

3.25 DIHED

Calling sequence : CALL DIHED (KEY, OPCODE, NAME ,OCVAL, NUMSTP, TEXT ATYPE, ANAME, IEXIT, IUNT)

Purpose : To enter data set header records.

Parameters :

In
KEY		Data set identification key (Integer)
OPCODE	Operation Code (Integer)

1 to create

2 to append (only valid for KEY = 1)

3 to build

NAME		Model, Substructure, or Loadcase name (Character*6)
OCVAL	Occurrence value (Real)
NUMSTP	Step number for loadcase (Integer)
TEXT		Descriptive text for load cases (Character*20)
ATYPE	Analysis type (Integer)

0 Static

1 Time Step Analysis

2 Frequency Analysis

3 Load Step Analysis

4 User named

ANAME	Analysis name (Character*10)
IUNT		Temporary file channel number (Integer)
Out
IEXIT		Error condition (Integer)

Use : This routine is called to enter data set header records, or a model header record. The type of header is indicated by the parameter KEY. Appendix 1 gives a list of the values which these parameters may take.

This routine cannot be called while data is still being entered for another data set. Routine DILIM is called to indicate the end of a data set.

If a model is currently active and DIHED is called to enter a new model, the routine DIBLD will be called by DIHED to construct the FEMVIEW display data sets where necessary.

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

IEXIT

Meaning

0		Successful call
29		Database has not been opened
32		Current error must be cleared up first
36		Model name must be non-blank
37		Model does not already exist, cannot append
38		Model already exists, cannot create
39		Assembly already exists, cannot build
111		A model dataset is still active on unit (iunt)
112		Invalid dataset header key
113		Invalid opcode
114		Cannot enter nodal co-ordinates, no model active
115		Cannot append nodal co-ordinates
116		Cannot enter nodal co-ordinates at assembly level
117		Nodal co-ordinates already entered for this model
118		For keys other than 1, opcode must be 1 (create)
119		Cannot enter element topology, no model active
121		Cannot append element topology
122		Cannot enter element topology at assembly level
123		Element topology already entered for this model
124		Cannot enter element sets at the assembly level
125		Cannot enter materials at the assembly level
126		Nodal co-ordinates must be entered before results
127		Element topology must be entered before results
128		Loadcase name must be non-blank
129		Error in writing to temporary file on unit (iunt)
193		Cannot enter results, no model active
211		Invalid temporary file unit number (iunt)
