Error in CFX solver

Hi CFD members

In my multiple fluid domain conjugate heat transfer analysis, i am getting error as

Error in subroutine FNDVAR :
Error finding variable DENSITY_FL2
GETVAR originally called by subroutine GET_MFLOIP_ZIF

I have given desity for all domains.

Could you please help me to rectify this error ???????

Thanks
Loordhu

Looks like a problem with material properties. You say you have defined the density, but have you set the specific heat, thermal conductivity and any other parameters needed for the analysis?

Thanks a lot for ur reply

I am dealing with 3 different fluid domain. If i give run considering 1 & 2 or 2 & 3 or 3 & 1, i am not getting that error. But if i consider all three domains at a time, i am getting error.

I checked all fluid properties. All are entered.

Thanks

Check the interfaces and use Sp1. Try to change between GGI and one to one.
