Hi everyone,
I am trying to make the attached model for my assignment in Simulink, but I keep getting the attached error when I am trying to set a 1/m gain. Anyone knows what is the problem?
Thanks for helping me.

Make sure that you are getting right value for variable in the gain block. According to me if you know the value m then use the final result of (1/m) in the gain block

I am not quite sure if that's the problem. I need to define m as a parameter for the gain, instead of just inserting the value. But I don't know how to do that.

  • In File menu go to "model properties-->Model properties"
  • Model properties window will be opened
  • In which under callbacks section click on InitFcn
  • Then specify the values in Model initialization function editor box
  • Then click on Apply-->OK
