SIGFPE in reactingFoam(LES)

I obtain a floating point exception when I run reactingFoam using a LesModel. From gdb:
Program received signal SIGFPE, Arithmetic exception.
0x01a9b232 in Foam::divide (res=..., f1=..., f2=...)
95 BINARY_OPERATOR(scalar, scalar, scalar, /, divide)
In 0 directory I don't assign a value for muEff, rho as well as for epsilon and I don't see the need to assign one in Les.

in reactingfoam you use the partially stirred reactor, which needs some fields like k or epsilon.
I'm new to Openfoam, but would like to use the PaSR for my case, also with LES turbulence model.
My Question is: Is there anyone, who already used reactingfoam with LES. How did you calculate epsilon?
Thanks for any answers.

whick LES model you are using??
I am new to Openfoam. I am simulating a simple jet (CH4) and coflow (air) problem but when i am using RAS model, jet is spreading and mixing well but when i tried to use LES model, jet is not spreading. Jet is going straight. no mixing is taking place and it is not looking LES from any angle. what would be the problem? what changes should be done to implement LES model in reactingFoam??
