I was thinking that initializer_subcompartments might be a more suitable name than initializer_flows as you are calculating initial values of the subcompartments for given flows.

I do not think that initializer_subcompartments is a better name, because e.g. the realistic initialization also initializes subcompartments. The naming should include that we are using flows for initialization.

The LCT model has been updated in the meantime, so small changes had to be made here
