Hello,
I'm working on a Simscape model, and I'm trying to implement an external force to my model.
I keep getting this error when running my simulation.
Can you please help find the reason why.
Thank you

Hi,
The input to the "External force to torque" block is [3*1] in size as it contains all the three components Fx, Fy, Fz in it.
Since the signal that is coming from the product block is [1*1] or scalar, hence there is width inconsistency and thus that block is not accepting the values.
The possible workaround is either you choose single component Fx, Fy, Fz from the properties of the block else, replicate the product block thrice and send it as an array.
For more info, you can take a look at this documentation page:
Hope it helps!
