Graphics display between visual task and surrounding area

Post by Christophe » Fri Oct 04, 2019 12:45 pm

Dear,
Point n°1
On my project I have a working area with 0.5meter from wall.
A visual task cover also the same area and the resulst are différents beween the two.
Average for workplane : 302 lux and min/average =0.24
visual task area : 304 lux and min/average = 0.53
Question 1 : why the results are differents ?
Question 2 : What is truth the result of the workplane or the result of the visual task ?
See enclosed documents with screenshots for example.

Point n°2
Also regarding the display graphic results the colors and isolines are differents between surrounding are and visual task area.
Sometime background graphic is displayed behind visual task sometimes not why ?
Also how with the interface is it possible to display one time ony visual task without surrounding and surrounding without visual task ?

Waiting for your feedback
Thansk in advance
Christophe SIMON

Dear Christophe,

We wonder if you could send us your evo project file. We would like to check the problem directly in this project. If the file is too big, you can send it to us via WeTransfer (www.wetransfer.com).
It would be of help if you could send us the link to this topic so that we could better assign this issue.
Our email address is 'Support@dial.de'.

Best regards,
DIAL Support Team

If it is ok, I would like to make a guess.
I think you get these differences because of different measuring meshes in your surfaces.
Evo sometimes sets them different, depending on how you place and cut the surfaces.

But you could try to manually set the same properties for the measuring grids on those surfaces and redo the calculation.
Then you should get the same results.

Hi,
Another example :
On the following example the result of the worplane and the task area (identical) are different.
Why workplane result table and in value grid min and max values are differents ?

Furthermore we can see also that the graphic result are similar on workplace and task area but not the table result ? ambiguous not ?
Waiting for your feedback.

Hi,

as Krose already said it has to do with different "grid settings".

On the workplane evo always uses the highest resolution (adaptive) the calculation delivers, so you will get every small spot with very high or low values, therfore you get similar average values but often more extreme min/max values. The calculation does not use a fixed grid to calculate the results so the Min/Max values might be located between the grid points and you will not see them in the value grid charting.
The visual task area uses the same calculation method but takes just the values into account that are located on the measuring grid (according to the standard). This will miss some spots that are located between the grid points. As the standard states that you should use this calculation grid Min/Max values between the grid points are not shown in the documentation for the visual task area.

To make it short:
Both values are correct, but they are not the same. You have very high resolution results on the workplane and results of the measuring grid according to the standard for visual task areas.

Best Regards
Kolja
