Input of units
All values are entered including its (actual available) unit. TrayHeart interprets the unit and signals errors by different colors of the cell.
The mechanism is actually just a detail - but it shows how well thought-out and practical the software is. It is therefore described in more detail below.
As long as only a numerical value is entered in the input cell, the standard unit (of the selected unit set) is displayed on the right-hand cell edge.
If a unit is entered which can not be interpreted or which does not match the physical properties of the input cell, the entry and the cell are highlighted accordingly.
All inputs (numeric value with unit) are stored; the cells also display these entries during later processing. The result outputs (screen, printout) are then displayed in the choosen unit set.
The output of values is independent of the entered units. For output you select a unit record (e.g., US or SI).
Input of data
At many points in the program, automatisms help you to choose a meaningful solution. These are geometry and surface relationships, shape formulas and design rules. Cells, which are presented with a "manual" button, display such automatically calculated values.
As long as the switch next to a cell is not pressed, the quantities are automatically calculated. E.g. for the geometry of a segment downcomer, the minimum area is determined.
Pressing the switch enables editing the default value. This automatically changes all the values of dependent cells. For the example of the segment downcomer, the area and weir length (as well as the related sizes) are recalculated online when defining the downcomer width.
TrayHeart is suitable both as a rating and a design program. In one case you come with a very small number of input to a meaningful result. In the other case, you can put in the exact geometry of the tower and get an exact description of the design.
Import of data
TrayHeart has interfaces for importing stream profiles from thermodynamics simulators:
- REP files from ASPEN +
- ChemCAD (Standard 3.5)
- Pro-II report files
Data from any other programs can be transferred via a configurable import from the clipboard. We provide also import interfaces for in-house simulators.
