I have a model of a mechanical system in simulink, which has a lot of parameters which are NOT variables mathematically speaking. eg. Mass, length of a body.
i have some fixed values for these parameters which do not change during the simulation. my model is having many user-defined blocks and in each block i have to initialize the same variables.
is there any method by which i can initialize variables in common for all user-defined blocks. OR may be i could initialize these variables in a file and extract it.
Yes, typically this kind of initialization is done using MATLAB code that is called from the model InitFcn callback, so that the code is run every time the model is compiled or run. If you want the parameters to be created only once when the model is open, you can use the PostLoadFcn callback.
