# What are appropriate values for Temperature and Loads Convergence Tolerance?

There is no default value in loads/temperature convergence tolerance. Tutorials recommend: for temperature (0.4 default); loads tolerances (0.04 default). In the most example files there is a Temperature convergence tolerance of 0.005. With this value I get the following severe error:

* Severe *CheckWarmupConvergence: Loads Initialization, Zone="zone1" did not converge after 25 warmup days.

* ~~~ *See Warmup Convergence Information in .eio file for details.

* ~~~ *...Environment(RunPeriod)="GRAZ - AUT IWEC Data WMO#=112400"

* ~~~ *..Max Temp Comparison = 0.22 vs Temperature Convergence Tolerance=5.00E-003 - Fail Convergence

* ~~~ *..Min Temp Comparison = 0.21 vs Temperature Convergence Tolerance=5.00E-003 - Fail Convergence

Is a temperature convergence tolerance of 0.4 a proper value?
