Dialog box after calculation

After finishing a calculation, Ebsilon shows by default whether the calculation has been successful, how long it took, and how many errors or warnings exist. Under “General Options“  “Calculation“ it is now possible to set if this message is to occur

• always (Yes)
• ever (No)
• only in the case of errors
• in the case of at least warnings
• in the case of at least comments

If "Show simulation progress" is selected (this is also the default setting for new models), a dialogue appears during the simulation that shows the convergence process and also allows a simulation to be cancelled prematurely.

The maximum number of iterations can also be subsequently adjusted upwards and downwards and the transfer of nominal values can be avoided.

Accept calculated global design values

The drop-down box "Accept calculated global design values" refers to the calculations only in the design mode:
In the design calculation, reference values (nominal values) are defined for the off-design mode. If you want to conduct an off-design calculation, these values must be saved as the specification values for the components (the blue entries). Depending upon the setting made in this tab, the export of the reference values from the design case is either done automatically or not done at all.

Select one of the following entries from the drop-down list "Accept calculated nominal values":

• No: Do not overwrite the nominal values of the active profile of your document with the calculated values.
• Yes: Overwrite the nominal values of the active profile (and all sub profiles) with the calculated values.
• Show Dialog Box: After the calculation a dialog box appears, to decide, whether the calculated values are to be imported or not.

If you do not wish to save the nominal values at present, you can do this later also by clicking on the button "Apply" or by the menu command
"CalculationàTake over Nominal-Values".

Local off-design and local design

The drop-down box "Accept calculated local design values" refers to the calculations only in the local design mode:

There was the possibility to exclude individual components from the design in a (global) design calculation by setting these to the mode FMODE = “local off-design“. These components had to be designed otherwise then (manually or in a separate model).

For individual components (currently these are 2, 5 to 11, 13, 15 to 17, 21 to 27, 29, 34, 35, 41, 43, 44, 61, 62, 70, 71, 73, 94, 107) there is a mode FMODE = ”local design“. For components where this setting is active, a design calculation is carried out at all times, even if the rest of the model is in off-design calculation mode.

If components in the model are in this mode, the question for an adoption of the reference values is posed also after an off-design calculation. The adoption, however, will take place only for the respective components and only for the calculated nominal values.

For adopting the reference values, it is possible to copy the calculated reference values to another profile. For this, after the question for the adoption of the reference values has been answered with “Yes”, a checkbox appears where the desired profile to which the reference values are to be copied can be selected.

This dialog, however, can also be hidden if you want to adopt the reference data always into the current profile or always into the main profile as a rule.

For this, there is a checkbox “Save nominal values“ in the general settings under Calculation/General. It has the following options:

• “No“ : the values are not adopted automatically and there is no checking (with the icon “Adoption of reference values“, however, the adoption can be caught up on later).
  
• “Write local design data to active profile“: the values are adopted into the current profile automatically without checking.
  
• “Write local design data into the root profile“ : the values are adopted into the current profile automatically without checking, if the entire calculation is carried out in
  design mode. In the case of local design, the reference values are copied into the main profile.
  
• “Show Dialog-Box to select profile to write to“ : it is checked whether the values are to be adopted, and if so, into which profile they are to be copied (this is the default setting).
  
• “Write full specification (including local design data) to active profile“ : the values are adopted into the current profile automatically without checking.
  
• “Write full specification (including local design data) to the root profile“ : the values are adopted into the current profile automatically without checking, if the entire calculation is carried out in design mode. In the case of local design, the reference values are copied into the main profile.
  
• Write local design data to reference profile
  
• Write full specification (including local design data) to reference profile

Collect equations during simulation / Only collect equations from validation-steps

Checkbox "Collect equations during simulation" --> list : "View"--> "Toolbars" --> "Equation Analysis"

Since the installation of this list is time-consuming, it is created only when the checkbox “Gather equation data“ is checked. If the list of equations is not needed, then this checkbox should be unchecked. The list is displayed below the model.

There is also the checkbox

Checkbox "Only collect equations from validation-steps"

The equality list shows how much the violation of the equation and the confidence interval of the violation are.

Checkbox "Only collect equations if equations-bar is visible"
