C code generation error in flexible multibody — at Initial Version

Reported by: Bruno Scaglioni Owned by: Lennart Ochel
Priority: high Milestone: Future
Component: Code Generation Version: trunk
Keywords: c code generation, flexible multibody Cc:

Description

The attached model is a flexible beam example, the model is quite involved and contains several tensor product, hence equations reach a lenght of 28000 characters, and OMC cannot perform symbolic derivation anymore. Nevertheless, several of the terms involved in these products are null and depend from null parameters.
In order to avoid problems with the lenght of the lines the annotation (Evaluate=true) is used and these options are given to the compiler:

setPreOptModules("evaluateReplaceFinalEvaluateParameters,removeSimpleEquations");
