Buildings.Controls.OBC.CDL.Reals.Sources.Validation

Collection of models that validate the continuous sources blocks of the CDL

Information

This package contains models that validate the blocks in Buildings.Controls.OBC.CDL.Reals.Sources.

The examples plot various outputs, which have been verified against analytical solutions. These model outputs are stored as reference data to allow continuous validation whenever models in the library change.

Buildings.Controls.OBC.CDL.Reals.Sources.Validation.CalendarTimeMonths

Validation model for the calendar time model

Buildings.Controls.OBC.CDL.Reals.Sources.Validation.CalendarTimeMonths

Information

This model validates the use of the Buildings.Controls.OBC.CDL.Reals.Sources.CalendarTime block for a period of a couple of months. This shorter simulation time has been selected to store the reference results that are used in the regression tests at a resulation that makes sense for the minute and hour outputs.

Buildings.Controls.OBC.CDL.Reals.Sources.Validation.TimeTable

Validation model for TimeTable block

Buildings.Controls.OBC.CDL.Reals.Sources.Validation.TimeTable

Information

This model validates the TimeTable block. It takes as a parameter a time table of the format

table = [ 0*3600, 0;
          6*3600, 1;
         18*3600, 0.5;
         24*3600, 0];

The block timTabLin applies smoothness method of linear segments between table points, periodically repeat the table scope.

The block timTabLinHol applies smoothness method of linear segments between table points, hold the last table points when it becomes outside of table scope.

The block timTabLinDer applies smoothness method of linear segments between table points, extrapolate by using the derivative at the last table points to find points outside the table scope.

The block timTabCon applies smoothness method of constant segments between table points, periodically repeat the table scope.

The block timTabLinCon applies smoothness method of linear segments between table points, periodically repeat the table scope. Table points is different so to ensure constant zero during time range of (0*3600, 6*36000).

table = [ 0*3600, 0;
          6*3600, 0;
          6*3600, 1;
         18*3600, 0.5;
