Hi Sherm,
Thanks for the quick reply. This does clear things up for me.

Best Regards,
Kishor.

Hi Sherm, Another question. Is there a difference between Assembler::assemble() and MultibodySystem::project(..,ProjectionOptions::PositionOnly) ? Do these two functions do the same thing ? Or perhaps project() expects that the errors in position and velocity level are not excessive ? Also, if I hav...

Hi Sherm, Is there any easy way I can perform coordinate projection from main() ? For a constrained serial chain type system given in ChainExample.cpp, one can use Assembler::assemble(state) and this drives the position level errors to zero. Are there any functions I can call from main() which also ...

<t>Hi Sherm,<br/> <br/> This clearly explains the results i was getting from my code. I suppose, in the current example, the easiest way for me would be to simply use state.setQ() and state.setU() directly. I should perhaps not include the Prescribed Motion constraint on the system at all since, i d...

<t>Hi Sherm,<br/> <br/> Just to follow up on this discussion. Right now, we have got the prescribed motion working with the RNA problem in Simbody and the system seems to behave as expected. I am now attempting to use it in my DCA solver. <br/> <br/> In main(), after defining the PrescribedMotion (t...

Hi Sherm,
I tried using getHCol() and it works out fine for my current purposes.

Thanks,
Kishor.

<t>Hi Sherm,<br/> <br/> What is the easiest way to obtain the H matrix in equation 5.2 described in the <br/> Simbody theory manual ? I am looking only at coarse grained RNA applications <br/> and expect just the regular joint types (free, rigid, revolute, spherical).<br/> <br/> The method i used pr...

Hi Chris,

Thanks for the quick response. You were right, I had unwittingly installed SimTK 1.5. instead of SimTK 2.0 version. I have got my code working already.

I am sorry for the trouble.

<t>Hi,<br/> <br/> I have recently installed the linux distribution of the simtk 2.0 core. However, I cannot get the code ExampleAdenylateMobilitiesVMD.cpp to compile. The error is following. <br/> <br/> class SimTK::RNA’ has no member named ‘setResidueBondMobility’<br/> <br/> I had a look at the hea...

Hi Jack,
Yes, I will certainly help in testing the Express version of SimTK.

Thanks,
