I am designing solenoid for charged particle tracing but I couldn't resolve for the error "cannot determine centre of the coil" under magnetic fields node.

Hi, do you have your Coil set to "Circular"? Did you select a circular edge in the "Coil Geometry" subnode of the Coil node? If that does not work, perhaps try the "Numeric" coil type. See these example models that may be helpful: https://www.comsol.com/model/magnetic-field-of-a-helmholtz-coil-15 and https://www.comsol.com/model/multi-turn-coil-above-an-asymmetric-conductor-plate-13777
