Velocity change under drag and other forces: small mass, large delta-t

[QUOTE="jrmichler, post: 6289801, member: 638574"] When the drag coefficient is a function of Reynolds number, it needs to be a variable in your simulation. You could try making the time step variable. Use the acceleration to calculate the next time step for a given percent velocity change. Start with about 10% to debug the program, then reduce for more accuracy. Program termination would be based on acceleration decreasing below a set value. It's not velocity, it's Reynolds number. And the Reynolds number of a sub-micron (30E-9 m is 0.03 micron) size particle is really low. [/QUOTE]
