I have an Energy Plus file with the following warnings in the .err report:

* Warning * Inside surface heat balance did not converge with Max Temp Difference [C] =2.059E-003 vs Max Allowed Temp Diff [C] =2.000000E-003

I'm doing the simulations considering PCM surfaces and timestep of 20/per hour (research recommendation) and ConductionFiniteDifference in the HeatBalanceAlgorithm object.

I would like to know how to solve the problem and this problem directly interferes with the results.

I have same error. What is unclear to me is that the reported Max temp diff (8.957E-005) is even lower than the Max Allowed Temp Diff [C] =2.000000E-003, so I really don't get it

@tassioluiz this is very similar to this post and this post. I'll leave yours open for now, since your model includes PCM and the other posts do not.

Let me know if the thoughts from the other posts resolves your warnings.
