BEGIN NEW DATA CASE C BENCHMARK DC-49 C Companion case to DC-32, which had MEMSAV=1 use. Development was first C documented in Volume X EMTP Memoranda, 3 July 1980, Pagination MSDO. C Node LOADA has a one-ohm resistor connected to FAULT, and this in turn C is connected to ground via switch number one. This fault switch was open C during DC-32, but will here be closed at 12 msec (the 1st step beyond C the backed-off switching time of 11.99 msec). $OPEN, UNIT=22 FILE=dc32to49.bin STATUS=OLD FORM=UNFORMATTED ! { (hold case) C $OPEN, UNIT=22 FILE=dc32.bin STATUS=OLD FORM=UNFORMATTED ! { (hold case) START AGAIN 1 .011990 9999 $CLOSE, UNIT=22 STATUS=KEEP $OPEN, UNIT=22 STATUS=SCRATCH FORM=UNFORMATTED MISCELLANEOUS DATA CARDS .000020 .018 .010 1 1 0 0 1 0 0 2 $OPEN, UNIT=4 FILE=dc32.pl4 STATUS=APPEND ! { C-like usage adds at end C The following step numbers are a continuation of DC-32, which simulated C 500 steps (DELTAT = 20 microseconds, TMAX = 10 milliseconds).
