I was searching in documents if there is a possibility to incorporate user-defined solvers on my model, including capabilities like choose dynamically between solvers during a simulation (example: change the solver when I switch from actuators on my model)
For now, I didn't find anything. I hope someone can help me in this issue.

The SystemBuild simulator currently cannot change solvers dynamically during a simulation.
What are the solver attributes or solver name were you intending to incorporate for your user-defined solver? (i.e. fixed step implicit solver, ...)
Internally the SystemBuild simulator has data structures for UserDefinedIntegrators, but they were not made public and hence not in the documentation.

I will use this application on AutoCode generation, wich support use of user-defined integrators, not in SystemBuild.
My need is dinamic change, not just the integrator algorithm, but as well modify the integration time step. I need to change the integration time step, when I receive a command from one of the variables in the model.
I will not intend to use variable-step integrators that return in time to calculate better accuracy.
I just need to modify the integration time step for the same integrator algorithm or using different algorithms with different integration time steps.
PS. I saw in documentation that AutoCode just support fixed-step integrator. I only need to know if my situation applies on that limitation.

Now, I´m using generation for integration with Veristand.
I found problems with some block during the procedure, but in general the integration was fine.
NI R&D promess some upgrades to correct the problems.
Be confortable to contact me any time.
