Solver properties#
Block appearance in REPEAT VISION#
The Solver properties block allows the user to specify solver parameters used when calculating the model.
If the model represents several unrelated physical systems, the diagram can contain the corresponding number of solver configuration blocks for each system separately. However, the presence of this block is not mandatory - a system of differential equations for a physical system for which solver settings are not specified will be solved using the default settings.
To link a block with solver settings to a specific physical system in the model diagram, it is sufficient to link it to any block that is part of this system.
