Solidworks Simulation: Model may not have adequate prescribed temperatures

Hi,

I'm having some problems doing a Thermal simulation. I did a first one succesfully and then I decided to include 4 pieces like this one:

After that, when I remesh and launch the study it pops up this error:

I have found on the forum similar error but not this one. I have deleted my temperatures and established again but it continues giving this error.

Does someone know what happens?

Thanks in advance
