PlasmaParams | Python Fiddle

# Parameters

electronDensity = 1.0 * 10**13
electronTemp = 1.0
cellCt = 2000.0
length = .5
injectRate = 7.12 * 10**13
timeStep = .01				#in ns

# Quantities

electronPlasFreq = 5.64 * 10**4 * electronDensity**(.5)
debyeLength = 7.43 * 10**2 * electronTemp**(.5) * electronDensity**(-.5)
cellSize = length / cellCt
maxTimeStep = 1.0 / 2.0 / (electronPlasFreq * 10**(-9))
fluxTS = injectRate * 10**(-9) * timeStep
oneStepDist =    (electronTemp * 1.60217657 * 10**(-19) * 2 / ( 9.10938291*10**(-31) )    )**(.5) * 100 * timeStep * 10**(-9)

# Output

print "Electron Plasma Frequency: "
print electronPlasFreq
print

print "Debye Length: "
print ("%.4f" % debyeLength)
print

print "max time step: "
print ("%.4f" % maxTimeStep)
print

print "flux rate: "
print fluxTS
print

print "one step dist: "
print oneStepDist
print

print "Cell Size: "
print ("%.8f" % cellSize)
if cellSize < .55*debyeLength:
	print "less than half of Debye length: SUCCESS"
else:
    print "not less than half of Debye length: FAILURE"
