What is the recommended alternative to SNOPT, post deprecation?
解决方法
Support for the SNOPT optimization solver will be deprecated from the Optimization Module at COMSOL Multiphysics 6.4.
If you have used SNOPT in the past, we recommend using the IPOPT optimization solver, which performs similarly.
With optimization solvers, it is always recommended to scale objectives and constraints so that they become non-dimensional, i.e. so they have no unit. Frequently, this is best accomplished by scaling an objective with its initial value and a constraint with the magnitude of its bound.
The flywheel profile optimization model illustrates the use of scaled objectives and constraints.
