Code Review

This pull request updates the MultiPhys operator in MueLu to correctly retrieve the boolean value of the 'repartition: use subcommunicators' parameter instead of using its existence check as the value. A review comment suggests wrapping the updated line to improve readability and comply with line length standards.

[gemini-code-assist]

This line is quite long (approximately 130 characters) and performs a redundant lookup of the parameter 'repartition: use subcommunicators' which was already checked in the preceding if statement. Consider wrapping the line for better readability and to adhere to standard line length limits.

Suggested change

	arrayOfParamLists_[iii]->set("repartition: use subcommunicators", paramListMultiphysics_->get<bool>("repartition: use subcommunicators"));
	arrayOfParamLists_[iii]->set("repartition: use subcommunicators",
	paramListMultiphysics_->get<bool>("repartition: use subcommunicators"));
