Hello,


I need a pressure "p" matrix of an external flow case with 1-2 million cells in Matrix Market (.mtx) format for solver development.


Is there a tool that allows to store a pressure matrix of a particular timestep in the Matrix Market (.mtx) format?

no idea what matrix market is, but you can convert the csr matrix produced by fvMatrix<> to the simpleMatrix<> class. That class follows the classical indicial i,j form
