WebA DEFINE_DPM_BODY_FORCE udf is used to implement this. The results are somewhat dependent on the Step Length Factor, as is the FLUENT default model. Careful selection of the Step Length Factor will minimize dependence on this model parameter. #include "udf.h" #include "dpm.h" #include "surf.h" #include "random.h" #define gasconst 1.38e-23 WebStep Length Factor: We can use it to control time step size for the motion of the particles—the more minor value results in higher trajectory accuracy. Length Scale …

WebMar 12, 2024 · The pseudo-transient method is a form of implicit relaxation (as opposed to explicit relaxation). In explicit relaxation you solve the equation but limit the variable change a posteriori. In implicit relaxation, you don't solve the original equations but relaxed equations. The relaxed equations limit the variable change because you inject the ... WebFor example, Initially we adopt step size 0.0005 and after 10 second of simulation we increase the step size to 0.001. After getting stability, step size changes to 0.005 when simulation was at 40 ...
