Default Floating point errors on a multi processor sim.
Posts: n/a

I would like to model 3D domain on multiprocessor machine. But I've a problem related with floating point errors on a multi processor simulation. The solution for my model seems to be to run on a single processor, i can see the velocity, pressure and the other parameters as a vector and contours. I have changed my whole 3D domain meshing into Polyhedra than opened it in multiprocessor machine(16 processors), after starting to iteration everything looks OK. But, when i want to see how the process is going on, how the vectors and contours of the domain is getting well, it shows only a black screen and gives an error message on fluent command line like; 'Floating points error...'

What does this problem related with? Is it related with multiprocessor or graphical issues or computational errors?
