Speed up compilation time Matlab simulink/simscape

Hello everybody,

i am modeling an electrical machine using simulink/simscape. More precisely, I am observing the thermal behavior. Thus, using the thermal domain of Simscape.

However, the compilation time is very long compared to the simulation time and takes about 99% of the whole simulation time.

Is there any option to speed up the compilation time? For example a pre-compilation of the block that no compilation is needed if parameters are changed.

I think using Rapid Accelerator mode just speeds up the simulation itself. At least it has no influence for my model.

Best regards

Felix

Hi @Felix Hoffmann,

I understand that you are trying to reduce the compilation time for your Simscape model. To achieve this, Simscape has run-time parameters, which are MATLAB variables or “Simulink.Parameter” objects that are run-time configurable. These parameters allow to skip recompiling the model when parameter values are changed. Simscape supports run-time configurability for most parameters that need a numerical value input. To determine whether a parameter is run-time configurable, you can review the settings for the parameter in the block property inspector. If a parameter is run-time configurable, you will see the property inspector set to the default setting, “Compile-time”. This can be changed to “Run-time” if necessary.

Please refer to the following documentation to understand more about run-time parameters.

There are a few other ways in which you can speed up the compilation of a Simscape model in general. You can use optimization techniques such as scalable compilation, incremental compilation, and memory or disk caching for model compilation.
