Release number limits

Post by Mahdiye Mirzai » May 25th, 2018, 12:46 pm

hello
I calculated a concentration twice. At first with changing in release number limits and after that without them. the results in ASCII files showed difference and when I calculated external dose for 1 year period, The maximum amounts are 2.4E-3 Sv in one case and 1.1E-4 Sv in another case. the setup that was use are shown below:
&SETUP
tratio = 0.75,
initd = 0,
kpuff = 0,
khmax = 9999,
kmixd = 0,
kmix0 = 250,
kzmix = 0,
kdef = 0,
kbls = 1,
kblt = 0,
conage = 48,
numpar = 50000,
qcycle = 0.0,
efile = '',
tkerd = 0.18,
tkern = 0.18,
ninit = 1,
ndump = 1,
ncycl = 3,
pinpf = 'PARINIT',
poutf = 'PARDUMP',
mgmin = 10,
kmsl = 0,
maxpar = 100000,
cpack = 1,
cmass = 0,
dxf = 1.0,
dyf = 1.0,
dzf = 0.01,
ichem = 0,
maxdim = 1,
kspl = 1,
krnd = 6,
frhs = 1.0,
frvs = 0.01,
frts = 0.1,
frhmax = 3.0,
splitf = 1.0,
/
Which one is correct calculation?

I believe you are saying you did two runs using different number of particles. I suggest doing some more runs with more particles. In general when you have enough particles for that run the result will not change much when you add more particles.
