Missing Function in ChCCollisionInfo.h

[Nicholas Richmond]

I'm working through some of the demos after downloading the most recent Windows installer package (Precompiled Project Chrono 3.0.0). I can get demo_FEA_basic.cpp to build and run, but when I try to build demo_FEA_contacts.cpp, I received an error stating that: 'SetDefaultEffectiveCurvatureRadius': is not a member of 'chrono::collision::ChCollisionInfo'

When I checked ChCollisionInfo.h (attached), the SetDefaultEffectiveCurvatureRadius function isn't defined. I noticed that the ChCollisionInfo.h available through the git repository does contain the 'SetDefaultEffectiveCurvatureRadius' function. It might make sense to build new precompiled binaries with the updated code such that the examples provided in the Tutorials are able to run with the precompiled Chrono packages.

Hi Nicholas,

The function SetDefaultEffectiveCurvatureRadius was added to the code after 3.0.0 was released. 

The issues appears to be that you are trying to build a demo from the current development branch against the Chrono libraries from the 3.0.0 release.  How/where did you get demo_FEA_contacts.cpp?

Hi Radu,

That makes sense. I was using the demo_FEA_contact.cpp from the Tutorials section of this site. Indeed, it looks like the demo uses code in the develop branch of Chrono. I compiled Chrono from the develop branch, and then the demo_FEA_contact.cpp built and ran perfectly.
