  • There is no image attached. But I suspect you are defining your terms as linctr's, but you are using nonlinear evaluations. You should use nlctr, and try to solve the nonlinear problem. – Baykal May 11 '20 at 13:55

The default implementation of abs() only accepts numbers. In order to make abs() for for expressions, you have to include the mmxnlp module. This is explained in the documentation here.

Note that this will change the type of your constraints from linctr to nlctr, so you have to change that in your code as well.

Finally, strict inequality is not supported. Instead > is interpreted as boolean operator. For a constraint you have to >=. If you really need the expressions to be different from zero then there is no other option than to use an epsilon: replace > 0 by >= eps for a small number eps.
