Compartment capacity


The Capacity property indicates the size of the SimBiology® compartment object. If the size of the compartment does not vary during simulation, set the property ConstantCapacity to true.

You can vary compartment capacity using rules or events.


Remember to set the ConstantCapacity property to false for varying capacity.

Events cannot result in the capacity having a negative value. Rules could result in the capacity having a negative value.

The Capacity property and Value property are identical.

Add a compartment to a model and set the compartment capacity.

  1. Create a model object named my_model.

    modelObj = sbiomodel ('comp_model');
  2. Add the compartment object named nucleus with a capacity of 0.5.

    compartmentObj = addcompartment(modelObj, 'nucleus', 0.5);
