However, simply changing the descriptor from D3Q19 to Q27 by: Quote: #define DESCRIPTOR D3Q27Descriptor doesn’t work. The compilation does not succed, because of an “undefined reference” to the descriptor. Is there a way to impement the D3Q27 structure? Best, Sumit February 10, 2017 at 11:38 am #2534 robin.trunkKeymaster Hi Sumit, for descriptors you can have a look at > src > dynamics > latticeDescriptors.cpp/.h/.hh. There should a D3Q27Descriptor already be implemented. To find out why it won’t compile the whole error message is required.
