Dear all,

I am trying to simulate radial inflow turbine which is having approximately 50lacs mesh.
I am receiving following error
1. ERROR #001100279 has occurred in subroutine ErrAction.
| Message:
| Floating point exception: Overflow
2. | ERROR #001100279 has occurred in subroutine ErrAction.
| Message:

Please help me , what is this about?

Search the forum for floating point error. Been asked a miliion times. In short your simulation has diverged.

hi,
G horrocks.
i did the simulation for Rotor-stator(using Cfx Turbo tools) without any errors.
Then I started the simulation for full assembly(Volute,Nozzle,Rotor,Diffuser) with same boundry conditions as of rotor-stator.I am getting the error.Can you please help me in setting the problem.

Search the forum on floating point error. There are many posts with tips on how to deal with this error. I really should write an FAQ on this one.
