Hello, I am trying to use Simulink's Full Car model, altered with the tire magic formula blocks so that, in the end, I can input a throttle curve, and get out acceleration, velocity, and tire slip ratios. However, I get the following error when I try to run: "Unexpected or invalid block connection. This can arise when a library block changes its underlying implementation to use a new domain that is incompatible with the original implementation. Check and reconfigure block connections to use a consistent domain."
Please find the attached file. The changes I've made have been primarily in the "Vehicle Load - Wheels - Road - Power Scope" block.

In your model, you have attempted to connect Simscape Driveline 1G blocks and Simscape Driveline 2G blocks using a physical connection. That can only be done using Simulink signals. The best thing to do would be to start with shipping demonstration sdl_car, which is implemented completely in Simscape Driveline 2G technology.

Type sdl_car at the MATLAB command prompt to open it.
