The "line" behind the shoch should look more spherical.
temperatureWind=constant=10000K
but I was using temp_t before.
densityWind propto 1/((dsqrt(vx**2+vy**2)*100000d0))
but it was propto 1/vamb**2 before.
[email protected]=100
but was 100000 febore.
I can see the problem from time=5cu
Rerun: twind=temp_t, outFrames=15, finalTime=15:
I dont see the inwards-moving shock.

THE PROBLEM REMAINS. tempRaise=0

t=0 AGB. Imediatly after that the conditions are that for a short jet
of
1.5 cu [160 yr]. Then, there is ONLY ONE TRANSITION to
the fast stellar wind. See Perinooto etal. 04. So:
tpPN=tUNUSED; smooth1=UNUSED;
tPN=40; smooth2=.04; tempRaise=1; cflv=.4,.35,.05
vT=1000./(exp(-2*.05*(x-40 ))+1)+200.
fig4
mDotT= -.5/(exp(-2.*.1*(x-20))+1)+.5 +0.00001
fig5
temp_t= 9000.d0*(1.d0/(dexp(-2.d0*.05*(time-40.))+1.d0))+1000.d0
fig6
sigma=0
density [wind] = mDotT*densFactor/vamb/((r*lScale)**2)/nScale/hMass
=> problem remains.
temp rise happens at time>3cu
run: tamb=10 K ; t_wind propto temp_t; finalTime=20.; tempRaise=0;
nScale=100; cflv=.6,.5,.4
plan: resume from frame 20 with tempRaise=1

amr problems. Caused by wrong set of refinement parameters:
Back to the spherical wind. No ionisation temp raise. BUNNY EARS?

SWEEPdata, Method: was 1,1,0,1,2,0,0;
is 1,1,0,2,0,0,0.

WERE:qTolerance = .5 .3 ...; FillRatios = .99 .99 ... ; wwind=40.
nSacle =100; TempScale=1000; ViscCD = 2
tempRaise=0
=> output: "setting method(4) = 1" [refers to SWEEPdataMethod component 4.
quick reran with it being 1
and the error is no longer displayed.]
comparison:
fig9
run: SWEEPdataMethod(4)=1. Output the same as in fig9 right.
run : SWEEPdataMethod(4)=0. output "setting method(4) = 1". Output the same as in
fig9 right.
run: SWEEPdataMethod(4)=1; SWEEPdataMethod(5)=2. Only diff with fig8 is that
here wwind=60 while there
wwind=40:
fig10
SO, SWEEPdataMethod(5)=0 DON'T SEEM TO WORK WITH COOLING

theories on the problem: bc @ proble.f90+lib/i_setbc.f90.
I see increasing negative vx values behind the bunny ears
idea: ambient region:
22: if ( vx(close to the boudary for ~2cells) vx<0)
then
vx(close to the boudary for ~2cells)=vx(close to the boudary for ~2cells
for i-1)
GOTO: 22

run: again: SWEEPdataMethod(4)=1; wwind=60.
change: SWEEPdataMethod(5)=1; iCooling=0
output: sweep method not setup for method(5) == 1 (src1D).
run: MaxLevel=1 to see if seatures in fig11 improve; iCooling=1;

No cells with strange values of either vx or vy.
Black density contour looks better.
RESOLUTION WAS THE PARAMETERS THAT HELPED HERE.
run: MaxLevels=2; finaltime=out_frames=15.; dtv=2e-3, 4.5e-2; cflv=.4,.35,.1.
Bad cfl reports and NAN at ~ tnext=0.5536E+01
run: dtv=1e-3, 2e-2; cflv=.4,.35,.1.;
result: bad cfl at 0.9716E+01. I stopped it. No sign of the uggly bubble
in fig9 left. Bunny ears remain and I see spurious negative velocities:
vx<0 close to both the bowshock and the -X boundary (left),
vy<0 close to both the bowshock and the -Y boundary (bottom).

ideas: iProtect=1; iCylindrical=1; MUSCL instead of SWEEP;
Modify either the ambs or the winds vel at angles ~0 or ~90 so that
evolution of wind is changed.

SEGMENTATION FAULT.
run: iScheme=1; imhd=T; iCylindrical=1.
SIMUL IS MUCH SLOWER.
run: using 16 procs instead of 32 because the W.Load report showed a lot of 0.00 values.
Then, the simul ran faster for the first .1 cu
and start slowing down afterwards, to the point where each timestep takes > 10sec
to execute.
tracer1 grows exponentially and it reaches ~3e6 @ t~.31cu.
run: tracer*[email protected]. Tracer1 is still > 10^4 and grows.
run: iCylindrical=2; based on my webpage annotation from 15dec09. Tracer1 is still >
10^4 and grows and simul get terribly slow
at~tnext=0.3346E+00
run: Commented the negative momenta killing commands at run (A), see above.

I have two r507 in bluehive, one update and one built from scratch.
r507-update. Manage to control de tracer fields growth (found when iCylindrical/=0) by
adding
q(i,j,k,1,nambtracer) = 1.0d0
q(i,j,k,1,nwindtracer) = 0.0d0
(8mar10-1)
q(i,j,k,1,nshocktracer) = 0.0d0
at the ambient section.
run: r507-new. Sim slows down without (8mar10-1). tracer ambient ~ 1e6; E~7e6 @
t~.33457.
run, r507-new: cycle command below the i do loops in b4step, thus b4step does nothing
to the q array.
Sim didn't slow down.
run, 507-new: iCylindrical=0.
Sim is much faster.
run, 507-new: iCylindrical=2; b4step {tracer wind=density@wind region; tracer
amb=denity@amb region;
negative momenta are not killed}.
sim slows down from t=.15 on.
run 507-new: windtracer=1 and abmtracer=0 at wind region; the tracers take the
opposite values at the amb region.
Sim speed starts fast but oscillates afterwards.
fixed grid doesnt really help much.
=========
run idem: iCylincrical=0; commented very last do loop at b4step; mintemp=2000. [was
1e-5];
maxlevels=1; mX=400^2.
Sim much faster and constant velocity.

SEE DOCUMENT "icylindricaL /=0 debugging"
run, grass: icylindrical=1; iprotect=1; mX=200**2; MaxLevel=1; MinTemp=10.
fig3
12 mar 10
run, bluehive: same but mX=400**2; MaxLevel=0.
fig4
SO THE FLAT SHOCK AT ~ 45DEG IS DUE TO MINTEMP.
run, bluehive: MinTemp=5; mX=256**2;MaxLevel=2;decomposeMethod=0;
decompopsition=4 4
fig5
fig6
SO THE MIN TEMEPRATURE IN THE GRID IS SET TO MinTemp*TempScale
run, bluehive: MinTemp=.05 so that tamb=500K; TempScale=10000.K
mX=256**2;MaxLevel=2;decomposeMethod=0; decompopsition=4 4 1;
Resampling the velocities within the wind.
17 mar 10
Rewritten resampling and source term implementation with Jonathan.
run, bluehive, 32 adams procs: mX=128^2 [was 256^2]; sample=8 [was 4];
MaxLevel=2 still;ViscCD=0
run, bluehive, 32 adams procs: Same as above but I've included momentum
protections @ PNwind.f90.
run, bluehive, 32 Adams p: same but mX=512^2 [was 128^2]
19 mar 10
============================================
run, bluehive, 16 Adam's p: same but iProtect=0.
=> more than 1000 steps report from the src from tnext=0.1060E+01.
The problem remains.
