Description Usage Arguments Value

The constructor to get a new object of class `Substance`

1 2 3 |

`n` |
A number giving the horizontal size of the environment. |

`m` |
A number giving the vertical size of the environment. |

`smax` |
A number representing the start concentration of the substance for each grid cell in the environment. |

`gridgeometry` |
A list containing grid geometry parameter |

`difspeed` |
A number indicating the diffusion speed in x and y direction (given by cm^2/h). For more complex setup define Dgrid. |

`advspeed` |
A number indicating the advection speed in x direction (given by cm/h). For more complex setup define Vgrid. |

`occupyM` |
A matrix indicating grid cells that are obstacles |

`Dgrid` |
A matrix indicating the diffusion speed in x and y direction (given by cm^2/h). |

`Vgrid` |
A number indicating the advection speed in x direction (given by cm/h). |

`diffmat` |
A matrix with spatial distributed initial concentrations (unit in fmol) (if not set, a homogenous matrix using smax is created) |

`template` |
True if diffmat matrix should be used as tempalte only (will be multiplied with smax to obtain cocentrations) |

`...` |
