Hi,All I am using FLUENT Fuel Cell Toolbox to model a single PEM fuel cell stack.When I tried to initialize the model, I got the following error messages. Error: prf-set-var: invalid flonum Error Object: nan
Anyone knows how to solve the problem? Does that mean that I didn't specify all the required material properties correctly? I am desperate. Please help! BC |

I have the same problem when I modified a case in fluent 13.0 and tried to read it in Fluent 12.1.4. I checked the case file is good by opening it in Fluent 13 multiple times. But with Fluent 12.1.4, it gives the same error message:
"Error: %prf-set-var: invalid flonum" Any clue whats going on? Thanks. Shrinivas |

Hi guys,
Did anyone fix this fluent bug? I'm running a simulation on Ansys 13 of an internal combustion engine and when I try to load the .cas and .dat files saved every 15 time step, this error message appears. Thanks in advance. All the best. Rob. |

Probably because of the different version of Fluent.

I too have the same problem.
I just considered the cylinder and given inlet velocity at one side and outlet pressure at the other side. 1. defined the surfaces as the temperature body 2. inlet air velocity 8 m/s. 3. trying to find the cooling response of the system. In cell zone BC when I define cylinder as fluid then there was no error, but I defined it as solid the error was showing as below Error - %prf-set-var: invalid flonum Error object - 1.£ inf Kindly anyone suggest what is the problem. Thanks in advance. |
