Hello maintainer!I want to use ikfast instead of KDL algorithm to solve the kinematics of the manipulator.But when I follow the tutorial, the following prompt appears:

When intra-layer reaction rate in CHR2 is too high, the initialization or the solver fails due to the small time scales.
In particular the characteristics time for reaction is 100 times less than th…

Hi there,
I'm solving the heat equation using finite difference method, in which an nonlinear solver is needed.
I found kinsol will be broken after several steps. The error is as follows.

Zero-dimensional reactor library is very useful for simple calculations. Since
these reactors do not accept the calculation of steady-state directly you must
integrate in time until to consider …

So at this stage I am starting to be uncertain exactly what is intended to work and what is not intended to work. At least here is a summary of the tests I have broken, and which works and which do no…

I'm interested in the OpenModelica FMU part. The current version of OMEdit supports euler and cvode solvers, and I hope to extend the support solvers for the FMU export such as dassl and etc. I've set…

Adding an adaptive half-explicit method (one file, not over-engineered) for solving the pendulum with invariants would be very helpful.

## Summary
@adowling2, Ryan and I are working on a concrete model to simulate a rotary bed adsorption process. The model is square, with no degree of freedoms, and can be solved by IPOPT. When I cont…

I want to calculate a diffusion problem in silicon where impurity peak concentrations are as high as e.g. Cp=1e20/cm³. The PDE has the same form as for heat conduction.
The result for Cp=1e10 looks r…
