The Solver category includes parameters for configuring a solver for a model. A solver computes a dynamic system's states at successive time steps over a specified time span. You also use these parameters to specify the simulation start and stop times.
On the Configuration Parameters dialog box, the following configuration parameters are on the Commonly Used tab on the Solver pane, or on the All Parameters tab in the Solver category.
Specify the start time for the simulation or generated code as a double-precision value, scaled to seconds.
Specify the stop time for the simulation or generated code as a double-precision value, scaled to seconds.
Select the type of solver you want to use to simulate your model.
Select the solver you want to use to compute the states of the model during simulation or code generation.
Specify the largest time step that the solver can take.
Specify the size of the first time step that the solver takes.
Specify the smallest time step that the solver can take.
Specify the largest acceptable solver error, relative to the size of each state during each time step. If the relative error exceeds this tolerance, the solver reduces the time step size.
Specify the largest acceptable solver error, as the value of the measured state approaches zero. If the absolute error exceeds this tolerance, the solver reduces the time step size.
At each time step use derivative information to improve integration accuracy.
Select the order of the numerical differentiation formulas
(NDFs) used in the
Select how the solver behaves during a reset, such as when it detects a zero crossing.
Specify the maximum number of consecutive minimum step size violations allowed during simulation.
Specify the method to compute the Jacobian matrix for an implicit solver.
Specify whether Simulink® executes blocks with periodic sample times individually or in groups.
Specify whether Simulink software automatically inserts hidden Rate Transition blocks between blocks that have different sample rates to ensure: the integrity of data transfers between tasks; and optional determinism of data transfers for periodic tasks.
Control whether the Rate Transition block parameter Ensure deterministic data transfer (maximum delay) is set for auto-inserted Rate Transition blocks.
Specify whether the real-time system targeted by the model assigns higher or lower priority values to higher priority tasks when implementing asynchronous data transfers.
Enables zero-crossing detection during variable-step simulation of the model. For most models, this speeds up simulation by enabling the solver to take larger time steps.
Specify a tolerance factor that controls how closely zero-crossing events must occur to be considered consecutive.
Specify the number of consecutive zero crossings that can occur before Simulink software displays a warning or an error.
Specifies the algorithm to detect zero crossings when a variable-step solver is used.
Specifies the deadband region used during the detection of zero crossings. Signals falling within this region are defined as having crossed through zero.
Select constraints on the sample times defined by this model. If the model does not satisfy the specified constraints during simulation, Simulink software displays an error message.
Specify the step size used by the selected fixed-step solver.
Specify and assign priorities to the sample times that this model implements.
Select the extrapolation order used by the
Specify the number of Newton's method iterations used
Enable concurrent tasking behavior for model.
