Hi Every one ,I m getting this error from my simulink controller,this because i ve changed the stepsize from (0.6 in input and 0.4 in output) to (0.2 in input to 0.1 in output). this changed to length of my stepsize from 540 to 1618.

   Error in port widths or dimensions. Output port 1 of 'CRS_Controller_170905/CRS Feedback
    Simulation/CRS_CombRateShapeV2/CRS_Control/IgnDly_Model/Ignition_Delay_Model/Physical/Droplet Diameter/bar_to_Pa' is a one
    dimensional vector with 1618 elements.

can anybody help?? thank you

From the error message, this issue seems to originate from the block that is connected to the controllers output. Try checking the block connected to "bar_to_Pa" to see if there are any parameters that are hard-coded with the value 540. Since the length of the controllers step is changing from 540 to 1618, a hard-coded parameter of 540 would need to be changed to the updated length of 1618.
