Ill-conditioned preconditioner.

Hello,
I started working with this software a few days ago, I have watched and read many tutorials. I am now simulating an oversimplified version of another project but when I try to compute the solution I always get the same error
"Ill-conditioned preconditioner Increase factor in error estimate to... " I am not sure what I am doing wrong since its a very simple geometry and very simple conjugate heat transfer problem.
Help on this will be kindly appreciated.
thank you

Hi
if I were you, I would remove the Heat transfer in Fluid module (delete), then switch the main NITF node from heat transfer in solid to heat transfer in fluid (as master model), then add a Domain Heat transfer in Solid node and select your solid "2"
Then use a normal or finer mesh

Good luck
