#add_grass command gives ValueError with gpu

#add_grass command gives
ValueError: index 32000 is out of bounds for array with size 32000.

I have tried different sizes but every time i got this error.
Operating system : Ubuntu 16.04
gprMax version : v3.1.5

@eyyupT can you supply the input file you are using, or a simple example that exhibits the behaviour.

#end_python:

this input file gives following error

I guess the number 120000 is the product of dimension in x and y coordinate (1000x120)

I tried above input file with below code to reduce grass area and to get rid of error
#add_grass: 0.1 0.04 0.3 0.9 0.08 0.3 1.5 0.28 0.32 10000 my_fractal_box

and the i got error with the number 32000 (grass area =800x40).
I run the simulation 80 times to get 80 A-scans. Error arise randomly not a specific simulation. Thus, you need to run simulation 80 times to get same error.

Thank you so much.

@craig-warren any improvement ?

[craig-warren]

@eyyupT can you provide a basic example of this behaviour that consistently gives the error. When I tested your examples the model ran without any error. What are the differences in your 80 A-scans?

[eyyupT]

@craig-warren antenna moves 0.1 cm in each simulation.

[craig-warren]

@eyyupT thanks, but can you provide a basic example (input file) that exhibits this behaviour consistently?
