General

Note Registry

The data for the general settings are stored under HKEY_CURRENT_USER by default.

Functions

List of last used files

The option ”List of last used files” defines, how many entries will be saved in the Registry-Database as "last used files". These files can simply be selected by choosing the ”File” menu and clicking on the file name.

Show contents of toolbars while resizing

The option ”Show contents of toolbars while resizing” determines whether the content of a toolbar (e.g. that of the Property Bar) should permanently be displayed while the toolbar is moved or resized.

If a slow computer has problems with displaying, deactivate this flag.

Internal Debug-Mode

The ”r;Internal Debug-Mode” activates certain printouts for debugging purposes. This feature is mainly used by Iqony Solutions for testing and error searching. These printouts may be changed from version to version.

Check for superposing components

If the check box ”Check for superposing components” is activated, you will get a warning message if two components are placed at the same position in the cycle.

This can happen by chance, for instance if you press the Ctrl-key while you click on a component (because "Ctrl + mouse movement" is used to copy an object). In the drawing you do not see that there are two components, but the calculation core will notice the second one. Generally, this will lead to errors like "missing mass flow" etc. because the second component is not connected. It would be worse if you put an input value twice on a line and change values just in one of them. According to Murphy’s law, the wrong one will be used for the calculation.

Therefore, it is recommended that you activate this check.

If you get this error message, select the object that is causing the trouble. You can use the magnifying glass to figure out this object. When you click on "OK", you will get this message again and again each time you click with the left mouse button anywhere in the drawing. There are two ways to break this cycle:

• as the corresponding object is selected, you can just press the "Delete" key to delete this object. Or you can click with the right mouse button to open the context menu and carry out some other action. 
• the message box does not appear again till you release the left mouse button. Therefore, it is possible, to click on the corresponding object (or on another object) and drag it away while keeping the mouse button pressed down.

Check for links with wrong type or wrong direction

If the check box ”Check for superposing links with wrong type or wrong flow direction” is checked, you will get a warning message if an ending of a pipe happens to be at the same position as a connection point, but it cannot be connected because

• the fluid types do not match
• two inlets or two outlets would be connected

If a connection cannot be made because the connection point is already connected to another line, the warning message is not issued.

If you deactivate this message, it may happen that in the drawing a component may appear as connected, but actually there is no connection. If the connection is essential, the calculation core will issue messages like "missing mass flow" etc., but, on the other hand, it may even lead to wrong results.

Therefore, it is recommended that you activate this check.

How to get rid of such a message box, is explained above.

Buffer size for loading and saving

A buffer size for loading and saving can be specified. Usually it is not necessary to change this setting.

If, however, a non-linear runtime behaviour is observed (e.g. when copying twice the number of objects takes significantly longer than twice the time), enlarging this buffer may help.

Timeout for OLE-Messages

"Timeout for OLE-Messages" determines for how long EBSILON^®Professional will be waiting for a response from the Server-Application.
