Current used in calculations as Current Density
When defining the electromagnetic condition "current" I think that AIM is actually using the value as current density!
When I enter 2 Mega Amps (yes 2,000,000 Amps) my simulation yields a current density of 15915816 Amps/m^2 in my copper vias. Yielding a total current of 2 Amps (should be 2,000,000 Amps). See my calculations and images below
# Of Copper vias: 4
Diameter of 1 Copper via = 200 um = 0.0002 m
Radius of 1 copper via = 0.0001 m
Area of 1 Copper via = 3.14159 * 0.0001*0.0001 = 0.0000000314159 m^2
Current = current density * Total Area = 0.0000000314159 m^2 * 4 * 15915816 A/m^2 = 2 A
***NOT EQUIVALENT TO THE 2,000,000 AMPS I ENTERED****
Therefore you have to enter current density for a known surface area to define the current you want!
Either the units for the current need to be changed to Amps per unit area, or the calculation needs to change to allow the user to input desired current values!
Can anyone else validate this?
