Hi, ive been using funkysetfields to set the following initial conditions through out my mesh. Ive posted this earlier in the funkysetfields thread, however, its not a problem with FSF.

Anyways, the condition is this:

Part: temperature1
 Putting "pow(pos().z,0.1)" into field T at t = "0" if condition "(pos().x <= 0.0105) && (pos().z <= 0.15) && (pos().z > 0)" is true

And this works when z is bigger than 19. However when i change to values smaller than 19 (which coincidentally, i really need to do). I have a conversion factor of 0.01 (im typing in cm, solving in meters). I get this error:

#0  Foam::error::printStack(Foam::Ostream&) in "/home/gustavo/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"

Floating point exception

In an effort to try and elucidate this, i got some tips from a fellow poster, if i run the condition as pos().z i get no error, and as expected the values vary from 0.0001 to 0.149. If i try the pow function with those loweest and highest values to the power i need, i get no error.

The error only appers when the pos().z is in the pow function for some values of z.

I really have no clue how to fix this. As i dont really understand whats going on. I am more than glad to post anything else that might help.

I really need help; thanks for your time.
