simmechanics joint initial condition tunable parameter

Hi,

Is it possible to configure initial conditions of joint block (e.g. initial position, velocity) as tunable parameters? I'm running the simulink model in Rapid mode. I need to configure the joint initial states as tunable parameters so that I don't have to rebuild the whole model every time I change the initial conditions.

Thanks.

Hi,

You will need to make the run-time parameters option visible if you have never used them before. The option to switch individual parameters from compile-time to run-time is colocated with each parameter that is run-time enabled.

Note that run-time parameters are not exactly the same as tunable parameters. Some features may vary slightly from one release to another.

Thank you!

This answer has really helped me in my endeavours!

Took far too long for me to find this out!

Kind regards,

Yes, you can. The initial conditions can be configured to be run-time parameters so that you can modify them between simulation runs without compiling.

Hi Steve,

Could you be more specific? I'm using Matlab 2018b. And I cannot find the way to configure the initial conditions of joint blocks to be run-time parameters.

Thanks.
