A run cannot be made because there is no vehicle solver DLL file in the simfile.

MATLAB与Carsim联合仿真时，出现下面错误：

1、Matlab/Carsim solver DLL not found, invalid port dimensions

2、A run cannot be made because there is no vehicle solver DLL file in the simfile. If you do have a solver DLL file, you need to specify its location on the Model screen.

解决步骤：

1、确认Carsim中选择的Matlab版本是与本机匹配的

2、Carsim中车辆模型的输入、输出重新选择一遍，重新生产Parsfile文件

Export Channels按照Import Channels同样操作一遍

此时，再执行Send to Simulink，就不会报错了
