Calculation fails with 3D diffraction for distances over 50m

[1816Ac]

Hey Openoise team,

I'm having an issue with an openoise simulation. (openoise v2.2 and QGIS 3.34 Prizer)
When using horizontal diffraction (e.g taking into account building height, 3D ) the calculation fails for distances over 50m.
QGIS returns the following message: "sorry process not complete. View the log file to understand the problem."
However the log file is blank.

2D calculation runs fine (horizontal diffraction only) whatever the distance.

Can you help me out? I attached a screenshot of the 50m calculation for your reference.

FYI building height is a decimal attribute of the "building.shp" polygon layer.

Thank you for your report.
If you send us the shape files (.shp, .dbf. shp .prj ) of the buildings, sources and receivers we can reproduce the error you reported to see where a possible bug is located.
The shapes files you find in the folder “data set for testing” do not encounter the problem you reported.
Apologies for the late reply
Kind regards
OpeNoise Team
