General Discussion / Re: very short process arrows
« Last post by pbeilschmidt on October 27, 2020, 03:49 PM »
Hello Lloyd,

great question, and I am sure it is of interest to many users. That's why I am answering in some more detail.
I also redid your little example to show 3 or 4 steps, what the issue is and how to get it fixed.

Nothing *you* are doing wrong here... just a general issue when drawing a Sankey arrow between two nodes that are located close to each other and have little spacing. In my example I left the grid on, so you can see the spacing is just one grid step (48 px).

In the first image the arrow from node "waste heat boiler" to "stack losses". I guess this arrow is later supposed to carry the difference of the waste heat input (dark red arrow from the bottom) minus the energy recovered (light red arrow to the right), so basically the losses.

The screengrab 2a shows what happens, when the arrow is drawn. A graphical artifact is produced, with "wings" protruding to the bottom and the top over the nodes. To understand why this happens, I have moved the "stack losses" node a little bit to the right, just temporarily (see 2b).

Explanation: Each Sankey arrow has two yellow waypoints. They mark the first segment of an arrow from the edge of the node where the arrow still runs vertically before it "allowed to" bend. The same is true at the destination (target node): the yellow waypoint is where the arrow comes in and then runs to the node vertically [the same principle applies for horizontal arrow connections at the node].

As you can see the yellow arrows are too far away from the nodes. The yellow arrow delimiting the first arrow segment has been moved away too far up from the node "waste heat boiler", the yellow point that marks the last vertical segment of the arrow before it connects to the node "stack losses" is too far down.
Actually they are so far away from their nodes, that they have intersected (crossed each other on the arrow line and switched sides). And this is just impossible to draw correctly.... hence the "wing artifacts".

So, how to solve this? What I did is to pull the yellow arrows closer to their respective neighboring node. In the last image (No 3) they are just a few pixels away from the node. The arrow can now run straight from start node over first and second yellow waypoint to destination node.
An alternative option would be to space the nodes a little more and move "stack losses" further away from the other node. However, leaving more space between the nodes is not always possible.

The default segment length can be set in the Options dialog on the "Diagram" page in the "Arrow" panel. You can try and set "Default Segment Length" from 40 px to - let's say - 10 px and see if that works better for you. Note that a change of the value in the options does not apply retrospectively for existing arrows, but only for the arrows being newly drawn.

This graphical issue of "very short arrows" is even worse, if you have arrow tails and arrow heads in combination with "fat" arrows. I hope this lengthy explainer can help you better manage the "very short arrows".

Hi,

When I try and make a very short process arrow , e-sankey always seems to get confused and tries to double the arrow back- see attached file, what am I doing wrong?

Technical Support / Balance Label - Invisible when no difference in/out
« Last post by pbeilschmidt on October 12, 2020, 09:46 AM »
A video on our YouTube channel on 'Balance Check & Balance Label' has garnered some interest. One user asked how to make the balance label disappear when there is no difference between the input flow quantity and the output quantity. This is actually the second example shown in the video (from 02:18 to 02:30).

I'll explain this here in the forum, because it could be of interest for other users as well.

The balance label is turned on for this process (option 'Display Balance Label') in the process properties. It first appears in the default configuration with three lines (Input, Output, Difference).

You can then click the balance label and in the properties panel change to 'Custom'. This will open a small text box, where you can specify how you wish the balance label to look like.

The keywords and operators used can be found in the user manual on pages 47 to 49.

In this case the keyword string used is
Difference: {DiffSumOutMinusSumIn} {DiffUnitName}||showOnlyForBalanceWarning

The first part
Difference: {DiffSumOutMinusSumIn} {DiffUnitName}
defines the setup of the label (when visible) to show the word "Difference: " followed by the actual difference of output flows minus the input flows, and the unit (e.g. 'kg').

Following the two vertical lines (so-called 'pipes', Alt 124) are operators. Here we set
||showOnlyForBalanceWarning
to indicate that the balance label should only be displayed if there is an actual balance warning.

The triggering of the balance warning depends on the setting in the Balance Check Configuration. It can be tested for an 'Exact' match (a very tiny difference between input and output would already trigger the balance warning), or you can define an absolute value for the tolerance, or a relative difference. The Balance Check Configuration is shown in the video at from 01:00 to 01:27).

Check it out. I will see if I can make the samples from the video available for download, and will link them here.

I've edited the e!Sankey.exe.config, e!Sankey starts with the correctly using the licenseserver. But it only starts correctly when copied after installation and first run.

When copied directly after installation on first run the e!Sankey.exe.config gets overwritten again due to the a post config ation per user. Copied after first run it works fine.

Is there a solution to have it copied during the first run. If not we can possibly use Ivanti (appsense ) to copy it afterwards but not everyone does have Ivanti.

Regards,
Wilbert

Hey Wilbert,

happy to hear that you like the license server.

The default setup routine for the e!Sankey desktop app does not have the option to set a license server name.

To define the license server name to be used with the client installation, you can pre-configure it in the e!Sankey.exe.config. In the <configuration> section search for the element <appSettings>. Then use the line <add key="FloatingLicenseServer" value="SERVERNAME"/>.

For more details and additional parameters see the ifu Floating License Service documentation page 6

The licenseserver works niceley.
We've made an installation package for the client software so we can deploy this to other computers. Are there any options to set the correct license server by installation? we've found a solution possibly but that's by copying files in %localappdata%, not that nice...are there any parameters that can be used to set the correct server by installation on the clients?

Thanks in advance.

Regards, Wilbert
