Graphical representation of the results

This functionality will display the configuration as a coloured pipeline. The configuration can be zoomed in and out, panned in any direction and rotated in any direction as well.

This mode mainly will be used to give an insight in the results like where are the largest displacements or where are the maximum stresses located. It can also be used to check input parameters.


Most functionality to be used is equal to the configuration mode, so please refer to the Common functionality where the possibilities are described in more detail.


The main difference with the configuration mode is the use of colours on the configuration. Blue colours represent low value elements, green elements have medium values and the highest value elements are red as can be seen in the 'Value histogram' below.



In the histogram the number of elements with a specific colour is indicated on the Y axis and the range of the values is on the X axis. This will give instant insight whether just a little amount of elements have high values (as is the case in this example) or a great deal of the elements are red.
Being a red element just means it has a high value, it does not automatically mean having (almost) a too high value.
Values are always absolute values: negative stresses are as bad as positive stresses in a (steel) pipeline. The same counts for the displacements, the sign only determines the direction.
By default values from zero up to the current maximum are shown. Un-checking the Start from 0 the current minimum will be used. These value can manually be altered.
A reference value can be assigned also. Any element with a higher value will have a purple colour.
Entered changes in the Min., Max or Reference value will be reflected in the histogram instantly and the Apply button will become enabled. Only after pressing the Apply button the configuration colours will be changed.
Pressing the Reset button will result in the default values for all fields.
When parts of the pipeline are in the shadow and the colours may become hardly visible, checking the Increased illumination will show the colours more intensive.
hmtoggle_arrow1How to check input parameters


Although input tables cannot be visualised their resulting values can be shown via the corresponding output tables.

Take for instance these soil values, which were generated using the soil model wizard.


The soil values on the HDD seem to be right.

But the values at the station still need some refinement.

In the next example the temperature input is checked via the T-DIF column in the LOADATA result table.

hmtoggle_arrow1Colour management


In case e.g. stresses are visualised, red coloured elements do not indicate they are overstressed. The elements just have the highest values. Below are two examples (1 and 2, subdivided into a and b).


1a and 2a show the colours depending on the actual maximal stress. Both colour schemes are identical, only the number of elements differ and of course the maximum value.
1b and 2b show the colours depending on the maximal allowable stress which is set to 340 N/mm2. The colour schemes now are totally different.


In example 1 the stresses are far below the allowable stress, so in 1b the 'worst' colour is green
In example 2 the maximum stresses are just beyond the allowable one. Having set the reference value also to the maximum allowable stress, part of the colour scheme 2b becomes purple indicating overstressed elements.




In the visualisation below 1a and 2a look very similar also, whereas 1b and 2b are totally different.

Setting the correct values for the minimum and maximum together with a thoughtful interpretation of the colours is essential in the visualisation.
