Hi,
it's actually much simpler than what you may think :)
The standard ADM1 digester model, called FixVolumeADU, is what, in the scope of WEST, is termed a [b]coupled model[/b] which means a 'super' model consisting of two or more sub-models.
The FixVolumeADU is associated to the digester icon:
[code](* icon = "anaerobic_digester" *)[/code]
and is made of 3 sub-models:
[code] sub_models <-
{
OBJ Trans_In : ASM1toADM1 ;
OBJ Tank : ADM1_Digester ;
OBJ Trans_Out : ADM1toASM1 ;
};
[/code]
The [b]ADM1_Digester[/b] is the model you are looking for, i.e. the ADM1 digester model stripped of the incoming and outgoing interfaces. But it's presently [b]not 'exposed' in the WEST GUI[/b] for the digester icon.
All you need to do is to hook it to the digester icon, as follows.

[code]CLASS ADM1_Digester EXTENDS ADM1_DigesterConversionModel WITH

[u]Change to[/u]:
[code]CLASS ADM1_Digester (* icon = "anaerobic_digester" *) EXTENDS ADM1_DigesterConversionModel WITH
[/code]
