The MEMC model configuration for MEMS
MEMS_config.RdThe MEMS configuration is based off of Robertson et al. 2019. This model uses LM for the DOM uptake, LM for POM decomposition, and LM for MB decay; see dynamics for more details.
Format
An object created from memc_configure, containing the following elements.
- name
MEMS
- table
table of the dynamics used by this model configuration; see dynamics for more details.
- params
data table of the model parameters; see memc_params for more details.
- state
vector of the initial state values; see memc_initial_state for more details.
