Dear Congshan Zhuo,
I was implementng the methods you and your colleuges described in: "Filter-matrix lattice Boltzmann model for incompressible thermal flows". Is the temperature you use in equation 41 the physical temperature or is it a dimensionless temperature defined between 0 and 1, like T = (T_physical - T_physical_min)/(T_physical_max - T_physical_min). Looking forward to you reply,
Kind regards,
