IsoSurface.Value error

Hi AltairHW

 

I'm using FEKO 14.410 EDU edition and experimenting with the script example https://www.feko.info/support/lua-scripts/radiation-hazard-iso-surfaces/radiation-hazard-iso-surfaces-wizard

 

When running this code I receive an error when setting p1.IsoSurface.Value = 41

'POSTFEKO 14.0.410-277905 (x64)
c:\Development\Workspace\win64_Maintenance\utilities\geometry\include\common_RangeOf.hxx (41): Assertion failed: !isEmpty() '

 

If I comment out this line the script completes without error.

I can't determine why p1 is failing to set the value.

What is strange is p2 is a duplicate of p1 and it will set p2 value without error.

 

 

p1 = app.Views:Item(views+1).Plots:Add(scaledNearField)             
p1.Visible = false
p1.PlotType = 'Iso-surface'
p1.Legend.Position = 'None'                                    
p1.Label = ('RMS_Public' .. append_to_label)
p1.Visualisation.Opacity = 40                        
p2 = p1:Duplicate()                               
p2.Label = ('RMS_Occupational' .. append_to_label)
p2.Visualisation.Opacity = 40

 

-- ERROR OCCURS HERE WHEN SETTING p1's isosurface value

-- If I comment out this line the script completes without error

-- note that p2 successfully sets the value without error!?

p1.IsoSurface.Value = 41

 

p1.Visible = true

 

-- p2 is a duplicate of p1

-- can set p2 value without error

p2.IsoSurface.Value = 92
p2.Visible = true

 

regards
