UP ?
I've got a problem with 'SimpleViscoelasticRelationships'. This
2d-functor needs 2 'PhysicalParameters' that are casted into
'SimpleViscoelasticBodyParameters' in the method 'go'.
I want to use BcpConnection that inherit from
SimpleViscoelasticBodyParameters for one of the parameters.
The problem is that call 'SimpleViscoelasticRelationships::go' fail
(before entering the function).
I've got the following message:
terminate called after throwing an instance of 'std::runtime_error'
what(): DynLibDispatcher: ambiguous or undefined dispatch for 2d
multivirtual function, classes: SimpleViscoelasticBodyParameters
BcpConnection
You need own 2d-functor "*Relationships" for your
PhysicalParameters (BcpConnection).
SimpleViscoelasticRelationships only for
SimpleViscoelasticBodyParameters,
see line 29 in SimpleViscoelasticRelationships.hpp:
FUNCTOR2D
(SimpleViscoelasticBodyParameters,SimpleViscoelasticBodyParameters);
It calculate InteractionPhysics (SimpleViscoelasticInteraction) from
PhysicalParameters of contacting bodys.
So, if you have own PhysicalParameters, you need own Relationships
for calculating InteractionPhysics from this parameters. (or you
can modify exant classes with take care of their default behavior
without changes)...
Thank for your answer Sega,
There is still something boring:
as I said, BcpConnection IS a SimpleViscoelasticBodyParameters.
If I write my own functor, it will do exactly the same job as
SimpleViscoelasticRelationships !
Besides, casting BcpConnection into
SimpleViscoelasticBodyParameters is possible
without any problem. Maybe the 'problem' come from the
DynLibDispatcher?
