Nesting and Particle Tracking

Hi Everyone,

I asked a long time ago on the inria forum the same question ( here ) but could not work on this since, so I am going to re-post it here.

I am trying to use CROCO with particle tracking and a nested grid. However I am facing a problem for the particle inside the child grid : They do not move !

I did 3 tests to initialize the floats module :

  • one floats.in file with all the particles inside the parent grid (Fgrd = 0), result : particles inside the child grid do not move,
  • one floats.in file with the adequate particles inside the child grid (Fgrd = 1), result : particles inside the child grid are well initialized but after the first time step the coordinates are set to 0,
  • two floats. in file (floats.in and floats.in.1), in floats.in.1 only the particle inside the nested area are declared, result : particles inside the child grid are well initialized but after the first time step the coordinates are set to 0.

Does/did someone face the same issue or do I miss a step ?

Thank you, Best regards, Marine
