Hello Foamers,
Hope you are doing well. I have come across another question in the realm of openfoam tutorials. Would you please tell me what is the role of DMD utility in openfoam? I have seen them in the pimpleFoam/laminar/cylinder2D, and attached one of them: Code:
// -*- C++ -*- stdmd01 { // Mandatory entries (unmodifiable) type DMD; libs (fieldFunctionObjects); DMDModel STDMD; field U; // Optional entries (unmodifiable) /* patch <patchName>; */ // Conditional mandatory entries (runtime modifiable) // Option-1 /* interval 5.5; */ // Option-2 /* executeInterval 10; */ // Optional entries (runtime modifiable) /* modeSorter firstSnapshot; */ /* nGramSchmidt 5; */ /* maxRank 50; */ /* nModes 50; */ /* fMin 0; */ /* fMax 1000000000; */ // Optional entries (runtime modifiable, yet not recommended) /* minBasis 0.00000001; */ /* minEVal 0.00000001; */ /* sortLimiter 500.0; */ // Optional (inherited) entries region region0; enabled true; log true; timeStart 10; timeEnd 1000; executeControl timeStep; executeInterval 10; writeControl onEnd; writeInterval 1; } // ************************************************************************* // |
