Error: prf-set-var:invalid flonum Error Object: nan0x7ffffe00 wat does this erro mean?

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.
