Dear Foamers,
In order to validate interFoam solver I have changed ddt schemes to from Euler to Euler1. As it is expected I got an error unknown ddt scheme Euler1. At the same time, I have 8 valid ddt schemes.
Than the using CoEuler, CrankNicolson, SLTS schemes give me an error like attempt to read beyond EOF. It happens despite the fact that it is semicolon at the end of this row.
The backward scheme gives an error only Euler and CrankNicolson ddt are supported.
When I used bounded scheme an error was like Ddt scheme not specified.
I used openFoam7 installed on Ubuntu 18.04.4 LTS.
By the way the same situation with the OpenFoam6 installed on Ubuntu 16.04.4 LTS
Would like someone help me to clarify this issue?
Any kind of help is highly appreciated.
Please see the attechments for more information.

CoEuler and SLTS need more entries: either the flux or density, and the maximum Co number. Check the implementation for details'

CrankNicolson needs the weight between explicit/implicit discretization. setting 0 is fully implicit, and 1 fully explicit.
