[sparta-users] Fix/adapt & transparent plane interaction

[(Student) - N. R. <C00...@it...>]

Hi Everyone,



I have been facing issues with transparent plane while using the fix/adapt command.

I’m reading a transparent plane to calculate mass flux at the outflow of my cylinder geometry, and am using fix/adapt based on particles.

The simulation stops as soon as the fix/adapt command line is invoked, with the following error message

“Grid Cells marked as unknown = 4”



Attached are the sample input files to reproduce error (in.circle_transparent input file)

However, if I don’t read transparent planes , the simulation runs perfectly with same fix/adapt command line (in.circle_no_transparent input file).

Is there a way to exclude transparent planes in fix adapt?

Looking forward to your suggestions.

Thanks a lot in advance!



Regards,

Nishita
