Hi CFDOnline openFOAM community,

I would like to implement a LUT that defines a changing boundary condition. The value of this table can change depending on time, but is often static for several timesteps, then read anew from a file. This data is 2D, defined in a file of n,m columns (n,m > 100) and the relationship to the grid is set by constants read in from a dict file. This LUT is then accessed at every timestep to set the values at a boundary (actually a source term). The geometry of this input data is fairly arbitrary, but has the appearance of multiple convolved gaussians. This data must be read from a file, and cannot be generated from a numerical approximation.

I am wondering if I can leverage any openFoam (.org v10) data structure to help with this, specifically wrt domain decomposition and parallel execution.

Thanks for reading.
