What's new in Smart 1.3.4

July 25, 2024

The main changes in this version relate to the presentation of tables and a new operation Export raw data. Further customization of tables (and graphs) is still on our wish list.

General

This version introduces new preferences related to tables and graphs. These new preferences are stored in file Smart.ini in the user’s profile. Default values correspond to previous behavior of Smart.

The main menu includes a new menu item Export raw data. This menu item is only available when a Table window is active. Then it exports the data shown in that table to a CSV file specified by the user. The format of Export raw data is more suited for automatic processing by other software than the format of Save as CSV.

Tables and graphs

When comparing data from another experiment (Compare > Experiment), Smart checks if that experiment belongs to the same model version. If not, Smart asks for confirmation.

For data from Compare > Measured data, Smart now reads variable names and scientific units from the data file. If the data file does not contain any header rows, the old style column names (series names for graphs) are still used as fallback.
An optional third row in tables specifies the source of data when comparing to another experiment of measured data.

For graphs with a custom independent variable (on the X-axis), data points for “measured data” are not shown anymore. They were meaningless.

Numeric formats for tables (and axes of graphs) can be defined under preferences now.

Table data can be saved to CSV files in two ways: as shown in the table (by Save as) and with more detail (by Export raw data).

Preferences

Extended the dialog with two new tabs.
Tab Tables and graphs defines the formatting of tables. Choice of numeric formats also applies to axes of graphs.
Tab Export data defines the format of CSV files created by Export raw data.

Known issues

Integration method RK4fixed does not combine well with discontinuities in formulas for state variables. At first sight the outcomes seem to be wrong. But in fact, this integration method combines derivatives at several points in the integration interval. In case of a discontinuity, this may lead to results that are mathematically incorrect. Variable step methods will at least reduce the step size around a discontinuity.

The order of existing variables in existing graphs is not changed when they are changed in the Define Output dialog. This issue is caused by the underlying graph component. As a work-around, one can add a table from the graph – implicitly carrying over all settings – and then add a new graph from that table.

Prints of listings and graphs do not always scale properly. Unfortunately, these are issues of underlying components, out of our control.

An early version of Smart supported customization of visibility of model components. This feature has not been maintained and is possibly broken. Please remove or rename any old .cst and .prv files that accompany your models.
