    Dear Devoploers,
    Hope all is well. I want to use the MRT-LES method to simulate the 2D-cylinder, so in the cylinder2d example, I just change the DESCRIPTOR to MRTD2Q9Descriptor, and change the BGKdynamics to “SmagorinskyMRTdynamics<T,DESCRIPTOR> bulkDynamics(converter.getOmega(), instances::getBulkMomenta<T,DESCRIPTOR>(), 0.1, converter.getLatticeL(), converter.physTime())”, there is no compiling problems, but it always diverges, please help with this,thank you!!!

    Why does it diverge? Is the problem at the boundary or in the bulk? Try to increase the smagoConst and see what is the results. Best Mathias

    Dear mathias,
    Thanks very much for your reply. I try to increase the smagoConst but it doesn’t work. I don’t really know what the problem is and how to resolve it.
