I have three requests:

Request 1:
Please add the misssing graphs of the input/output tables from the old theoretical manual of PLE-micro-CAD in the new Ple4Win manual.


Request 2:
Please add the missing documentation about the element length from the old theoretical manual of PLE-micro-CAD in the new Ple4Win manual.
I have attached a PDF in this message about this old documentation.


Request 3:
Add extra loadfactors columns in the internal overpressure [PRESS] input table in Ple4Win, so that the loadfactor 1.25 can be manually changed to a higher value in case of the NEN 3650-2 (i.e. in (valve)stations) or in case of the Pipeline Handbook of Rotterdam. Now the factor (in case of the NEN 3650-2) is internally increased in the Ple4Win program by 1.25 for the internal design pressure only. If the General analysis method is used, the loadfactor of the LOCASE table is used (conform NEN 3650-2 it is 1.15), which means that the NEN 3650-2 factor 1.15 instead of 1.25 is used for the hoop stress (BC 2), which is not correct for the internal design pressure only. Try to standardise this in the PRESS input table by adding the loadfactor columns only for the hoop stress (BC 2), which is used in the General and NEN 3650-2 analysis method. For other loads in combination with the internal overpressure (i.e. BC 4) the LOCASE table loadfactor should always be used. In the output table two columns of PRESS values included the loadfactor should be presented: one used for BC 2 in output table LOADATA in the PRESS column and one used for BC 4 in output table INTFOR in the F-AX column.

Another way is to increase the LOCASE loadfactors input table with an extra column for the internal design pressure only (BC 2). Please make loadfactor jumps at Idents possible with multi-rows (so that the current 1-row input table is replaced and consistent with other input tables in Ple4Win) in the LOCASE table and by adding two columns for every loadcase.

Is it possible to extend the GROUP list with Tees+Connects, see printscreen below:
[attachment=545]

The text in the group menu should be changed then:
'Tees (Branch)' should be replaced with 'Tees+Connects (Branch)'
'Tees (Run)' should be replaced with 'Tees+Connects (Run)'
'Tees (all)' should be replaced with 'Tees+Connects (all)'

Currently PLE (version 4.2.3 and lower) isn't showing the CONNECTS nodes in the tee groups, see printscreen below. I want to see for example displacements at certain connecting nodes. Now one has to manually scroll to the concerned connect node(s).

This extension is very simple to add in the list and would be very helpful.

Thanks.]]>

I find that it is quite inconvenient to use the multiple graphic if there are more than two graphics and if I would like to check the details.

For example, I have present the pipe profile, subsidence and stress in one multiple graphic. In case the configuration is quite long and complex, it is not possible to zoom in to check the detail in order to have a direct idea where is the overstress.

Simplify to say, is it possible in multiple graphic that could work the same as single graphic, which could zoom in and out?

If in a pipeline different materials are used which is often the case when installing a new pipeline, there is a limitation in strength for each material.

Wish: to be able to enter different Y-references for a certain X-interval.

The easiest way to do this, is to add the white color to the set of colours that are already present in the program.

P.S. When a section of the pipeline falls under NEN 3651, the stresses and deformations are also multiplied by a certain safety factor. An other Y-reference applies for this section too.

To show what I am aiming for, I have added two images to this thread. I adjusted one of these images, so now it shows that no calculated stresses exceed the allowed stress according to NEN 3650.

Last I had a project to calculate a pipeline number 1 with Ple4Win with a certain condition. A other pipeline number 2 was lying next to the pipeline number 1 and the distance between these pipelines would be 100 mm. The condition was therefore that the horizontal displacement (U-Y-LOCAL) of the pipeline number 1 in Local Y-direction should not exceed 100 mm (preferable value: max. 80 mm).
See attachment, the displacements U-X, U-Y, and U-Z in Function 5: Pipeline Behaviour are all given in the Global direction. My wish is to show these displacements not in the Global coordinate system, but rather in the Local coordinate system. Why? Because:
The Global displacements U-X, U-Y and U-Z are today hardly used as results, where to my findings Local displacements are more important than the Global displacements. The actual information of U-X, U-Y and U-Z can only be used for a straight pipeline. Today the pipelines are more complex with horizontal bends.
A SingleGraph of the Global displacements does not show the real displacement of the pipeline after a horizontal bend. Even though, after the pipeline has had a horizontal bend, there is a actually way to calculate the displacements of U-Y and U-Z in Local direction by making further calculation to calculated the Y- and Z-components of U-LAT. But why do that if the displacements U-X, U-Y, and U-Z could be shown in Local direction.
For a Global view of the displacements the user can see the schematics of the pipeline.
And with U-Y given in Local direction and by making a SingleGraph I could see directly if 80 mm of 100 mm has been exceeded. This is also important as proof for clients.
If after this you still think that Global displacements are more important than Local displacements, then I would like in DISPLAC a way for the user to see U-X, U-Y and U-Z in Local or / and Global direction.

Could is be possible to add a row in Multi-Graph data definition? (The row ID4 would then be shown double.)
This is to add a value for the Y-reference for a certain first pipeline traject and an other for a certain second pipeline traject.

Pipeline trajects are declared by X(min) and X(max). Could it be possible to toggle to node for example.

Thank you.

In Function 4.2 Pipeline Loading it is possible in table SUBSIDE to choose the shape Block, Left, Right or Double.

It would be great if you can also choose one of these shapes with a certain length given by the user in the tables SET-Z, SET-Y, SET-X. Till then it is only possible to have linear soil displacements in these tables.

For projects I mostly solve this problem in Ple4Win by putting the soil displacements with a certain shape (e.g. a double) not in e.g. table SET-Z, but in table SUBSIDE. By doing this I also have to correct the standard uncertainty factor in table SUBSIDE from 1,5 to 2,0 for the soil displacements.

I hope to see the tables SET-Z, SET-Y, and SET-X being extended in a new version of Ple4Win with (unselected) shapes.

Thank you.]]>

Wish would be to improve the warning message, for example by: Angle tee an adjacent 'node 111 or elem 112' 7.4 deg.

This kind of modification can also be applies for other relevant warnings, like different settlements in one connect. This with the intention of making the program more user-friendly.

Because NEN 3651 is an addition to the standard NEN 3650, the current calculation method in PLE4WIN, which is based on NEN 3650, should be only expanded for NEN 3651. ]]>
