Examples and How To

Simulate Biological Variability of the Yeast G Protein Cycle Using the Wild-Type and Mutant Strains

This example shows how to create and apply a variant to the G protein model of a wild-type strain.

Simulate Model of Glucose-Insulin Response with Different Initial Conditions

This example shows how to simulate the glucose-insulin responses for the normal and diabetic subjects.

PK/PD Modeling and Simulation to Guide Dosing Strategy for Antibiotics

This example shows how to perform a Monte Carlo simulation of a pharmacokinetic/pharmacodynamic (PK/PD) model for an antibacterial agent.



Use doses to model different dosing regimens.


Use variants to store alternate parameter values and initial conditions of a model.

Model Simulation

Simulate dynamic models using various solvers.

Choosing a Simulation Solver

SimBiology® uses a solver function to compute solutions for a system of differential equations at different time intervals during model simulation.

Accelerating Model Simulations and Analyses

You can accelerate the simulation or analysis by converting the model to compiled C code.


Troubleshooting Simulation Problems

Troubleshoot SimBiology simulation errors, such as the Integration tolerance not met error, by changing the solver or tolerances.
