v674 v675 244 244 ||[=#PA0201 PA0201] ||dz=... <= 0.0 || The value given for [../inipar#dz dz] must be greater than 0.0. || 245 245 ||[=#PA0202 PA0202] ||grid anisotropy exceeds threshold given by only local horizontal reduction of near_wall mixing length l_wall starting from height level k = ... . ||The grid-dependent mixing length {{{l_grid}}} ( ''= '''Δ''' = (Δx Δy Δz)^1/3^'' ) becomes larger than 2.7 * dx or 2.7 * dy starting from the reported height level {{{k}}}. Although PALM will not abort due to this warning, the chosen grid setup might lead to untrustworthy results. The reason for this is an unfavourable choise of grid anisotropy. To avoid this, make sure that the values of [../inipar#dx dx], [../inipar#dy dy], and [../inipar#dz dz] do not differ too much from each other. In case of grid stretching, the settings of [../inipar#dz_stretch_level dz_stretch_level] and/or [../inipar#dz_stretch_factor dz_stretch_factor] should be changed to ensure a smaller difference between {{{dz(k)}}} and {{{dx}}} and {{{dy}}} at the reported height level. || 246 ||[=#PA0203 PA0203] ||inconsistent building parameters: index_left_bwall=... index_right_bwall=... =... byn=... nx=... ny=... || The setup of the single building ([../inipar#topography topography] = '' 'single_building' '') yields a too narrow building or the building walls are positioned outside of the model domain. Please check the [../inipar#topo building parameters] in your parameter file. ||246 ||[=#PA0203 PA0203] ||inconsistent building parameters: index_left_bwall=... index_right_bwall=... index_south_bwall=... index_north_bwall=... nx=... ny=... || The setup of the single building ([../inipar#topography topography] = '' 'single_building' '') yields a too narrow building or the building walls are positioned outside of the model domain. Please check the [../inipar#topo building parameters] in your parameter file. || 247 247 ||[=#PA0204 PA0204] ||no street canyon width given || If [../inipar#topography topography] = '' 'single_street_canyon' '' is given, also a canyon width must be given by either specifying [../inipar#canyon_width_x canyon_width_x] or [../inipar#canyon_width_y canyon_width_y] in the parameter file. || 248 248 ||[=#PA0205 PA0205] ||inconsistent canyon parameters: index_left_cwall=... index_right_cwall=... ngp_cx=... ch=... nx=... ny=... || Due to [../inipar#canyon_width_x canyon_width_x] the setup of the single street canyon ([../inipar#topography topography] = '' 'single_street_canyon' '') yields a too narrow canyon or the canyon walls are outside of the model domain. Please check the [../inipar#topo canyon parameters] in your parameter file. ||
