60
930111 Added "progname" variable to keep name of invoking command.
62
931012 Removed altitude < 0. test to support gear development. EBJ
63
931214 Added various pressures (Impact, Dynamic, Static, etc.) EBJ
64
931215 Adopted new generic variable structure. EBJ
65
931218 Added command line options decoding. EBJ
66
940110 Changed file type of matrix file to ".m" EBJ
67
940513 Renamed this routine "LaRCsim.c" from "ls_main.c" EBJ
68
940513 Added time_stamp routine, t_stamp. EBJ
69
950225 Added options flag, 'i', to set I/O output rate. EBJ
70
950306 Added calls to ls_get_settings() and ls_put_settings() EBJ
71
950314 Options flag 'i' now reads IC file; 'o' is output rate EBJ
72
950406 Many changes: added definition of default value macros;
73
removed local variables term_update_hz, model_dt, endtime,
74
substituted sim_control_ globals for these; removed
75
initialization of sim_control_.tape_channels; moved optarg
76
to generic extern; added mod_end_time & mod_buf_size flags
77
and temporary buffer_time and data_rate locals to
78
ls_checkopts(); added additional command line switches '-s'
79
and '-b'; made psuedo-mandatory file names for data output
80
switches; considerable rewrite of logic for setting data
81
buffer length and interleave parameters; updated '-h' help
82
output message; added protection logic to calculations of
83
these parameters; added check of return value on first call
84
to ls_cockpit() so <esc> abort works from initial pause
85
state; added call to ls_unsync() immediately following
86
first ls_sync() call, if paused (to avoid alarm clock
87
timeout); moved call to ls_record() into non-paused
88
multiloop path (was filling buffer with identical data
89
during pause); put check of paused flag before calling sync
90
routine ls_pause(); and added call to exit() on termination.

95
* Revision 1.4.1.7 1995/04/07 01:04:37 bjax
96
* Many changes made to support storage of sim options from run to run,
97
* as well as restructuring storage buffer sizing and some loop logic
98
* changes. See the modification log for details.
100
* Revision 1.4.1.6 1995/03/29 16:12:09 bjax
101
* Added argument to -o switch; changed run loop to pass dt=0
102
* if in paused mode. EBj
104
* Revision 1.4.1.5 1995/03/15 12:30:20 bjax
105
* Set paused flag to non-zero by default; moved 'i' I/O rate flag
106
* switch to 'o'; made 'i' an initial conditions file switch; added
107
* null string to ls_get_settings() call so that default settings
108
* file will be read. EBJ
110
* Revision 1.4.1.4 1995/03/08 12:31:34 bjax
111
* Added userid retrieval and proper termination of time & date strings.
113
* Revision 1.4.1.3 1995/03/08 12:00:21 bjax
114
* Moved setting of default options to ls_setdefopts from
115
* ls_checkopts; rearranged order of ls_get_settings() call
116
* to between ls_setdefopts and ls_checkopts, so command
117
* line options will override settings file options.
120
* Revision 1.4.1.2 1995/03/06 18:48:49 bjax
121
* Added calles to ls_get_settings() and ls_put_settings(); added
122
* passing of dt and init flags in ls_model(). EBJ
124
* Revision 1.4.1.1 1995/03/03 02:23:08 bjax
125
* Beta version for LaRCsim, version 1.4
127
* Revision 1.3.2.7 1995/02/27 20:00:21 bjax
130
* Revision 1.3.2.6 1995/02/25 16:52:31 bjax
131
* Added 'i' option to set I/O iteration rate. EBJ
133
* Revision 1.3.2.5 1995/02/06 19:33:15 bjax
136
* Revision 1.3.2.4 1995/02/06 19:30:30 bjax
137
* Oops, should really compile these before checking in. Fixed capitailzation of
138
* Initialize in ls_loop parameter.
140
* Revision 1.3.2.3 1995/02/06 19:25:44 bjax
141
* Moved main simulation loop into subroutine ls_loop. EBJ
143
* Revision 1.3.2.2 1994/05/20 21:46:45 bjax
144
* A little better logic on checking for option arguments.
146
* Revision 1.3.2.1 1994/05/20 19:29:51 bjax
147
* Added options arguments to command line.
149
* Revision 1.3.1.16 1994/05/17 15:08:45 bjax
150
* Corrected so that full name to directyr and file is saved
151
* in new global variable "fullname"; this allows symbol table
152
* to be extracted when in another default directory.

* Fixes from Cameron Moore:
586
* I've attached 3 diffs against files in FlightGear to fix some printf
587
* format strings. The changes are pretty straight forward. Let me know
588
* if you have any questions. (BTW, I'm using gcc 2.95.4)

594
* Revision 1.4 2001/03/24 05:03:12 curt

* SG-ified logstream.

* Revision 1.3 2000/10/23 22:34:54 curt
599
* LaRCsim c172 on-ground and in-air starts, reset: all work
600
* UIUC Cessna172 on-ground and in-air starts work as expected, reset
601
* results in an aircraft that is upside down but does not crash FG. I
602
* don't know what it was like before, so it may well be no change.
603
* JSBSim c172 and X15 in-air starts work fine, resets now work (and are
604
* trimmed), on-ground starts do not -- the c172 ends up on its back. I
605
* suspect this is no worse than before.
608
* Balloon (the weather code returns nan's for the atmosphere data --this
609
* is in the weather module and apparently is a linux only bug)
610
* ADA (don't know how)
611
* MagicCarpet (needs work yet)
612
* External (don't know how)
614
* known to be broken:
615
* LaRCsim c172 on-ground starts with a negative terrain altitude (this
616
* happens at KPAO when the scenery is not present). The FDM inits to
617
* about 50 feet AGL and the model falls to the ground. It does stay
618
* upright, however, and seems to be fine once it settles out, FWIW.
621
* --implement set_Model on the bus
622
* --bring Christian's weather data into JSBSim
623
* -- add default method to bus for updating things like the sin and cos of
624
* latitude (for Balloon, MagicCarpet)
630
* -- all data members now declared protected instead of private.
631
* -- eliminated all but a small set of 'setters', no change to getters.
632
* -- that small set is declared virtual, the default implementation
633
* provided preserves the old behavior
634
* -- all of the vector data members are now initialized.
635
* -- added busdump() method -- SG_LOG's all the bus data when called,
636
* useful for diagnostics.
639
* -- bus data members now directly assigned to
641
* src/FDM/Balloon.cxx
642
* -- bus data members now directly assigned to
643
* -- changed V_equiv_kts to V_calibrated_kts
647
* -- bus data members now directly assigned to
648
* -- implemented the FGInterface virtual setters with JSBSim specific
650
* -- changed the static FDMExec to a dynamic fdmex (needed so that the
651
* JSBSim object can be deleted when a model change is called for)
652
* -- implemented constructor and destructor, moved some of the logic
653
* formerly in init() to constructor
654
* -- added logic to bring up FGEngInterface objects and set the RPM and
657
* src/FDM/LaRCsim.cxx

745
* Revision 1.2 2000/04/10 18:09:41 curt
746
* David Megginson made a few (mostly minor) mods to the LaRCsim files, and
747
* it's now possible to choose the LaRCsim model at runtime, as in
749
* fgfs --aircraft=c172
753
* fgfs --aircraft=uiuc --aircraft-dir=Aircraft-uiuc/Boeing747
755
* I did this so that I could play with the UIUC stuff without losing
756
* Tony's C172 with its flaps, etc. I did my best to respect the design
757
* of the LaRCsim code by staying in C, making only minimal changes, and
758
* not introducing any dependencies on the rest of FlightGear. The
759
* modified files are attached.
