Hi,

I am trying to calculate the PMV and PPD indexes in openfoam. I run the tutorial case "hotComfortRoom" and the PMV PPD values were calculated. Then I tried to calculate those values in another simulation starting from an already calculated velocity and temperature fields, therefore I set the simulation only for 1 timestep and I had this error

#0  Foam::error::printStack(Foam::Ostream&) at ??:?
#1  Foam::sigFpe::sigHandler(int) at ??:?
#2  ? in "/lib/x86_64-linux-gnu/libc.so.6"

This is the controlDict file

application buoyantSimpleFoam;

startTime 10000;

stopAt endTime;

endTime 10001;

type comfort;

clothing 1;

executeControl writeTime;
}
}

Do you know the cause of this error? the simulation has velocity and temperature values compatible with the calculation of the indexes.
Alternatively there is a post-process function to calculate those indexes?
