How to access the basic values?

[avrachan1]

Dear Community,

In any lattice boltzmann simulations, we have (x,y,z) location of the lattice nodes and n values associated with the populations.

This data should be is N*d*n matrix where N is the number of nodes, d the dimension and n the number of populations.

How can I access and print this data?

I need this for debugging and I can’t seem to find a way to do it in a straightforward manner.

Thanks.

You can access the physical location of each discrete lattice location using the CuboidGeometry::getPhysR method. If you need this in the described matrix format you can generate it using this information by e.g. assigning a globally unique cell ID as a combination of global cuboid index and block-local cell ID (obtainable via BlockStructure::getCellId).
