I am trying to simulate three particle of different sizes and properties (mainly biological particles) in COMSOL particle trajectory module. The system has to operate through some voltage V and the particles experiences different forces and ultimately moves. However, model is showing many errors:-
1.) Only single particle is under simulation despite defining all the particles
2.) Unable to calculate the forces which was added to the physics (eg, drag force, electric force, etch)
2.) Despite giving step time range(0, 1, 5) sec, model only converge up to 1 sec.
Can anyone help me with some tutorial similar to this? Or What am I missing in this?
Thanks

Some suggestions for you:
Particle Definitions- Verify accurate definitions for all particles in terms of sizes, charges, masses, and other properties.
Physics Settings- Confirm inclusion of relevant physics interfaces (Fluid Flow, Electric Fields, Particle Tracing) with proper configuration for particle sizes.
Force Calculation- Check expressions for drag force, electric force, etc., ensuring correct definitions of variables and parameters.
Solver Settings- Adjust solver settings, focusing on the time-stepping method, time step size, and tolerance values. Smaller time steps may enhance accuracy.
Initial Conditions- Provide precise initial conditions for particles, including positions and velocities.
Meshing- Ensure a well-defined mesh with appropriate settings and resolution to capture particle behavior.
Check for Errors- Review solver logs and error messages for insights into convergence issues.
Documentation and Tutorials- Refer to COMSOL documentation and tutorials, specifically for Particle Tracing in Fluid Flow.
Contact COMSOL Support- If issues persist, reach out to COMSOL support for personalized assistance.
