Calcium ion flow with dynamics.

Parameters
  • size (int, tuple of int) – The ion size.

  • keep_size (bool) – Keep the geometry size.

  • C0 (float, Array, Initializer, Callable) – The Calcium concentration outside of membrane.

  • T (float, Array, Initializer, Callable) – The temperature.

  • C_initializer (Initializer, Callable, Array) – The initializer for Calcium concentration.

  • method (str) – The numerical method.

  • name (str) – The ion name.
