gams:equation_infeasible_due_to_rhs_value

The complete error message in the lst file is:

**** Exec Error at line ...: Equation infeasible due to rhs value **** INFEASIBLE EQUATIONS ... ...

There is the model attribute `tolinfeas`

you can set, e.g.: `model.tolinfeas = 1e-5;`

This attribute is initially set to `NA`

, in which case GAMS will use a value close to the machine precision. For example the equation:

a.. 0*x =e= 0.0001;

will be infeasible. This can be reversed using

mymodel.tolinfeas = 1e-3;

which will make the above equation feasible. Other model attributes changing internal GAMS tolerances are: `tolinfrep`

and `tolproj`

.
