effect.

DESCRIPTION OF FILES GENERATED BY THIS CASE:
cylstif.ALL = Input data for BIGBOSOR4-type of preprocessor.
correponding to discretized entire panel.
cylstif.CBL = Contains part of cylstif data base.
For further information about files generated during operation
of PANDA2 give the command HELPAN FILES.
Next, give the command BIGBOSOR4LOG followed by BIGBOSORALL.
BIGBOSOR4 to be used to find buckling of the panel with
all stringer parts modelled as flexible shell segments. The
buckling load factors from this rather elaborate model should
be compared with those calculated from PANDA2
(The input for PANEL is saved in the file, cylstif.PAN. The
cylstif.PAN file is as follows:)
-------- cylstif.PAN file: input for PANEL ---------------n
$ Do you want a tutorial session and tutorial output?
314.1600
$ Panel length in the plane of the screen, L2
0
$ Enter control (0 or 1) for stringers at panel edges
2
$ Enter control (1=sym; 2=s.s.) for boundary condition
1
$ Enter ILOCAL=0 or 1 or -1 or -2 (Type (H)elp), ILOCAL

$ Number of halfwaves in the axial direction [see H(elp)],NWAVE

$ How many eigenvalues (get at least 3) do you want?

This is a long file and is not listed here to save space.
----------------------------------------------------------------------PART 2.2 Execute BIGBOSOR4 using the file, cylstif.ALL, as input,
in this particular run a prismatic model for LOCAL buckling
Next, we must run BIGBOSOR4. We copy the file, cylstif.ALL,
to another working directory and execute BIGBOSOR4 there.
cd (to new working directory)
cp ../(old working directory)/cylstif.ALL .
