Text Report Validation Results (for Ebsilon Quick Method)

 

The results of the quick validation of Ebsilon were stored earlier as an ASCII file.

For compatibility reasons, this report has been left in the format, in which it was generated earlier in the DOS version of Ebsilon. It is available only in German.

The report is generated by the menu command "Data"à"Measurement data"à"Output"à"Validation Results (ASCII)".

However, it is also possible to set the automatic generation of this report after every calculation. This setting is done under "Extras"à"General Options" in the tab "Calculation", by activating the check box "Save Results of validation as ... VAL file".

The Excel report is always created in the same folder as the model file, with the name

            "Model_results.xls",

where "Model" is replaced by the actual name of your Ebsilon model. If this file already exists, it is overwritten without any message.

The report looks like as follows:

The header line shows the calculation type (simulation or validation), the model name and the calculation time.

The table contains a list of all measurement values (component 46) in the model, a row for each measurement value. The columns in the table show

 

• the serial number (not relevant)
• the names of the measurement points
• the type: an alphabet, which indicates the measured quantity
  • P = Pressure,
  • T = Temperature,
  • H = specific enthalpy,
  • M = Mass flow,
  • Q = Power or heat flow,
  • S for all others,

   

• the use of the measurement point:
  • 0, if the measurement point is not used at all (deactivated),
  • 11, if the measurement point is used only in validation (redundant measurement point),
  • 12, if the measurement point is used in simulation and validation.

   

• the weighting of the measurement point for the validation (specification value WMV),
• the measurement value (specification value MEASM),
• the calculated value (result value RESULT).
• the plausibility limit in % (specification value ICONF)
• the relative deviation of the measurement value from the validated value. Since Ebsilon assumes that the validated value is the "correct" one, it indicates a negative deviation, if the measurement value is too low, and a positive deviation, if the measurement value is too high.
• a question mark “?” indicates the measurement values, for which the relative deviation exceeds the plausibility limits.

 

Hint: This report always uses the default unit system with "bar", "°C", "kg/s", "kW", "kJ/kg", regardless of the unit system selected on the screen or the one used by the individual components.
