Flexcom > Data Inputs > $LOAD CASE

Purpose

To indicate that an analysis is to be restarted from a previous run.

Theory

Refer to Restart Analyses for further information on this feature.

Keyword Format

A single line defining the restart type, file name and database option.

LAST=File Name [, TYPE=Restart Type] [, OPTION=APPEND]

Restart Type can be DYNAMIC/STATIC or CONTINUATION. OPTION=APPEND is appropriate only for a CONTINUATION analysis. Restart Type is set to DYNAMIC/STATIC by default. The only entry relevant for frequency domain dynamic analysis is File Name.

Table Input

Input:	Description
Type:	This option allows you to specify the restart type. There are three available types, New Loads or BCs (the default), Continuation - New Database, and Continuation - Append. See Note (b).
Restart File:	The name of the analysis from which the present run is to be restarted. This may be input in terms of the analysis name (e.g. Example1-Static) or the full path of the analysis (e.g. C:\Flexcom\Example 1\Example1-Static). See Note (d).

Notes

(a)Most restarts involve the addition of new loads or BCs such as current or waves, and for this you use the New Loads or BCs restart type. Occasionally, a restart is performed which is simply a continuation of the previous run, and for this you can use either the Continuation - New Database or Continuation - Append. Continuation - New Database simply means that a new database is created, while Continuation - Append means that the results from the previous analysis are contained with the restart analysis results in the restart analysis database. An example here might be where a regular wave analysis is found not to have reached steady state, and must be continued for further wave periods.

(b)The only input which is relevant for frequency domain dynamic analysis is Restart File. The Type option pertains specifically to the time domain.

(c)If a file has spaces included in the file name i.e. (sample 1.keyx) then in order for the full filename i.e. “sample 1” to be consider for the restart it must be enclosed by inverted commas.
