Hi, I want to solve continuity equation in COMSOL.
and also I want to import the volume charge (surface charge) as a text file to COMSOL. the continuity equation defined in "Electric Current" module is not complete. How can I define that by mathematics or maybe another module ?? Can I define it as an ODE equation?? and after that the problem is how can I import the charge deposition rate??! Is there any way to do this?
the geometry is 2D.
Dear Neda Mousavi
absolutely, you can define the continuity equation as ODE or PDE in 2D geometry. Also you can import the txt file or excel file to comsol ( you go to difinitions> Right click> functions>interpolation>import).
you can check this link:
