Hello,
 

I am not able to find any specific information in the Knowledge Base about what's included in the log file when running a motion solve simulation.
More specifically, about the Time specific infos written (ex:  Time=3.409E-03; Order=1; H=3.409E-03 [Max Phi=5.269E-16])
I assume this info is not written at every integrator timestep, so when are they written? (every X integration steps? or something else? )
Moreover, what does the Max Phi corresponds to? H is for the time step, but what is Max Phi for?

Thanks a lot

To get more information at each integration step, you can turn on the debug output in the simulation settings.  This significantly increases the size of the log file.  We also offer a "Tuning and Customization" course for MotionSolve that covers the log file in a bit more detail.

 

Max Phi really isn't documented externally.  Max Phi represents the maximum error in the constraint equation.  However, I find that I don't really this this value for debugging runs that are not converging or for optimizing solutions. 

 

If you facing difficulties getting convergence on a solution, please feel free to reach out to our normal support channels.  We are here to help.
