Using the Optimization Module for geometry examination

Geometry optiization 4.3a
Simple 1D sold state battery problem (in COMSOL)

Done with assistance from COMSOL
M = length of anode 320 nm
L = length of solid electrolyte 1500 nm

objective function = external voltage
time to 2000 sec (time dependent)

If L & M are listed with the mins and the max, no problem.

However if they are coupled - L+M= 1820 nm there seems to be no way to include this in the optimization module.

Does anyone any any ideas?

Thanks

Hi Arthur,

not sure about this, but have you tried to define the length of L to be 1820-M?
And you solve only for M then with a min (>0) and max (<1820).

Best regards,
Frank
