+## [Setting initial conditions that depend on parameters](@id dsl_description_parametric_initial_conditions)
 It is possible to set the initial condition of one (or several) species so that they depend on some system parameter. This is done in a similar way as default initial conditions, but giving the parameter instead of a value. When doing this, we also need to ensure that the initial condition parameter is a variable of the system:

 An alternative approach to avoid the issues of using mixed floating point and
