• Implement variable list for swan
• Implement variable list for dflowfm
• Implement variable list for subgrid
• Implement variable list for delft3d

Required functions (serverside)

A model that is run by an MMI server should implement at least the following functions:
From BMI:

Model control:

• initialize
• update
• finalize

Timestep:

• get_time_step
• get_time_units
• get_start_time
• get_current_time
• get_end_time

Model information:

• get_attribute
• get_input_var_names
• get_output_var_names

Metadata:

• get_var_pointer # return the (void) pointer to the variable
• get_var_type
• get_var_rank
• get_var_shape
• get_var_attribute(name, attribute) # 'units', 'standard_name', 'long_name'

Set vars are not required as we have direct access to the pointer and can overwrite memory as we please. Variable pointers won't be accessed while the update is being called.

Functions that can be called by the model are:

• log(LEVEL, message)

Required functions (clientside)
