turbJet tutorial crashing immediately after dumping restart files

[Filipe Brandao]

Hi, I am trying the turbJet case with some modifications and I am noticing that the solution always crash 1 step after dumping restart files. It does not seem a "physical" crash due to the solution naturally blowing up because the same happen even after changing the frequency of which restart files are written in "writeInterval"

I believe it may be related to the data communication between the turbJet and turbPipe coupled cases. My .par files are pretty much the same for the turbJet and turbPipe coupled cases:

turbJet:

[GENERAL]
#startFrom = turbJet0.f00001 XUPT time=20
stopAt = endTime
endTime = 100

dt = 2.0e-3
timeStepper = bdf2
extrapolation = OIFS
variableDt = no
targetCFL = 3.8

writeControl = runTime
writeInterval = 10

filtering = hpfrt
filterWeight = 10
filterCutoffRatio = 0.9

[MESH]
numberOfBCFields = 2

[PROBLEMTYPE]
equation = incompNS
stressFormulation = yes

[PRESSURE]
residualTol = 1e-04
residualProj = yes

[VELOCITY]
residualTol = 1e-06
density = 1
viscosity = -19000

[TEMPERATURE]
advection = no
rhoCp = 0
conductivity = -1
residualTol = 1e-6
residualProj = yes

turbPipe:

[GENERAL]
startFrom = turbPipe0.f00008 XUPT time=0
stopAt = endTime
endTime = 100

dt = 2.0e-3
timeStepper = bdf2

writeControl = runTime
writeInterval = 10

filtering = hpfrt

filterCutoffRatio = 0.9

[MESH]

[PROBLEMTYPE]

[PRESSURE]
residualTol = 1e-04
