temperature/loads Convergence Tolerance

Hey, there is no default value in loads/temperature convergence tolerance. Tutorials recomment: for temperature (.4 default); loads tolerances (.04 default). In the most example files there is a Temperature covergence Tolerance of 0,005, with this value i get the follwing severe:

* 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? Thank you very much!!

temperature/loads Convergence Tolerance

Hey, there There is no default value in loads/temperature convergence tolerance. Tutorials recomment: recommend: for temperature (.4 (0.4 default); loads tolerances (.04 (0.04 default). In the most example files there is a Temperature covergence Tolerance convergence tolerance of 0,005, with 0.005. With this value i I get the follwing severe:

following severe error:

temperature/loads Convergence ToleranceWhat 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.
