[Scilab-users] Using Modelica generic block MBLOCK in Xcos

[Clément David]

Hello,

Same question again :) : are you sure that you define all variables on
the diagram context ?

The "do_eval" update the block values merging the diagram context and
the updated context argument to set the expected block's values.

To view the definition of do_eval, just type : edit("do_eval") on
Scilab.
