Hi all,
My question is about how to create a model in comsol combining movement and electrical force.
Let's say i have two liquid metal drops(one with V=0 and other with V>0). there will be some electric force between the drops.
If i will use a fluid flow physic, and an electrostatic physic together, i will be able to calculate the force between the drop in the initial state and apply it on the drops in the fluid flow physic. now if i will run a transiant simulation i will see the drops moving and getting close to each other.
After the drops are getting closer, the force should enlarge too. but the problam with this simulation is that i can only simulate the electric force in the beginning of the simulation and it does not consider the change in the drops positions.
My question is how can i consider the physical change (location) in the electrostatic model during the transiant simulation ?
thank you all for answering !
