#3202 closed defect (fixed)

world.g override does not propagate

Reported by: crupp@… Owned by: adrpo

Component: Frontend Version: trunk

Description

When overriding world.g, the override does not propagate to models from Modelica.Mechanics.MultiBody. Consider this example:

loadModel(Modelica);

simulate(Modelica.Mechanics.MultiBody.Examples.Elementary.Pendulum, simflags="-override world.g=1.0");

// Override works here
val(world.g, 0);
// Does not work here, should also be 1.0
val(body.g_0[2], 0);

The defect seems to stem from the replaceable function gravityAcceleration in MultiBody.Parts.Body. If this function is replaced with world.g*world.n then the override works as expected.

Tested in r24986.

Yes. Unfortunately in some cases we replace the parameter with its value even if we should do that only for structural parameters (array sizes, conditions of conditional components, etc).

Seems to be working now. I'll close it so that you don't need to worry about it any more.
