v629 v630 355 355 ||[=#PA0312 PA0312] ||Time step has reached minimum limit. \\dt = ... s Simulation is terminated.\\old_dt = ... s\\dt_u = ... s\\dt_v = ... s\\dt_w = ... s\\dt_diff = ... s\\u_max = ... m/s k=... j=... i=...\\v_max = ... m/s k=... j=... i=...\\w_max = ... m/s k=... j=... i=... ||The time step is determined according to the CFL criterion to assure a stable numerical solution. This error message means that the required minimum time step, determined from the three velocity components, is several orders of magnitude smaller than [../d3par#dt_max dt_max], or, in other words, that at least one of the velocity components got too large. Due to the large number of complex reasons it should be noted that this list is not complete, but it is intended to give general hints how to proceed in case of this error message. First, check for a unrealistic value of [../d3par#dt_max dt_max] in the NAMELIST file. Moreover, this error message may indicate for unrealistic settings of e.g. [../inipar#bc boundary conditions] or other NAMELIST parameters. For very small vertical grid spacing [../inipar#dz dz] this error might also occur if [../inipar#roughness_length roughness_length] >= [../inipar#dz dz]. Please also check if this error appears if you run without USERCODE. To compile and run the PALM and USERCODE with DEBUG-options might also give sometimes valuable hints. 356 356 To be continued.|| 357 ||[=#PA0313 PA0313] || illegal value for parameter particle_color: ... || The parameter [../dvrpar#particle_color particle_color] allows to bind the displayed particle color to certain flow quantities.
