How to overcome the error “computed saturation temperature <= 0.0” when using variable saturation temperature in evaporation-condensation model?
This error arises when the evaluation of saturation temperature for the local absolute pressure value, based on the user-inputs for the saturation curve, goes below 0 [K]. If this error is encountered, a check of the saturation data or curve needs to be performed based on the method used to provide the saturation curve (piecewise-linear, tabular data, UDF, polynomial).
Please refer to this document for some of the scenarios resulting in this error and their solutions.
