[Jerome Duriez <duriez@xxxxxxxxxxxxxxx>]

Hello. I now become this message during a simulation :

"DynLibDispatcher: ambigious dispatch, could not determine which 
multivirtual function should be called"

In fact the simulation runs but with this message written a lot of times 
per iteration, leading to a very slow rate of iterations per second 
(plus the unpleasant feeling that something is wrong...). I've found 
that this is because of this particular paragraph of the .xml :

<engines _className_="InteractionPhysicsMetaEngine"  label="" 
functorNames="[[CohesiveFrictionalBodyParameters 
CohesiveFrictionalBodyParameters CL1Relationships]]">
               <functorArguments size="1">
                   <functorArguments _className_="CL1Relationships"  
betaR="0.12" setCohesionNow="0" setCohesionOnNewContacts="1" />
               </functorArguments>
</engines>


And more precisely it seems to be due to the use of "my" 
CL1Relationships (simulations with CohesiveFrictionalRelationships for 
example run well) but I didn't find the mistake (moreover before my 
updates I could use these Relationships).

   Does someone could explain me more precisely the sense of the output 
message to help me to find what is wrong ? Thanks

Jerome
