CombineSolution
Combine two solutions using concatenation or summing of solutions or by removing solutions.
Syntax
model.sol(sname).create(fname,"CombineSolution")
model.sol(sname).feature(fname).set(pname,pvalue)
Description
This feature combines solutions by concatenation or summation. The concatenation can, for example, take two time-dependent solutions solver over different time spans and combine them into a single time-dependent solution including all times from both solutions. You can also remove solutions. Stationary solutions are not possible to use. The following properties are accepted:

ascend
Sort eigenvalues in ascending or descending order, if sorteigvalues is set to true.
sorteigprimarily
realpart | imagpart | realpartmagnitude | imagpartmagnitude | absval

A single expression as weight for the summation (when weightsmethod is set to oneexpr).
When weightsmethod is set to listexpr, use setIndex with the properties wsolnum. weightlistexpr, and weightlistexpractive to specify the index (solution number), lists of weights, and active flags, respectively, for the case with a list of weights for a weighted summation. See setIndex(), and Methods Associated to Set, SetIndex, and the Various Get Methods for more information.
