求助，，，

我在跟MATLAB联合方针的时候在ADAMS建立的模型总是出现：
WARNING: MOTION MODEL_1.MOTION_1 has been declared to depend on the VARVAL function.
Motions should only be functions of TIME.
WARNING: MOTION MODEL_1.MOTION_2 has been declared to depend on the VARVAL function.
Motions should only be functions of TIME.
WARNING: MOTION MODEL_1.MOTION_3 has been declared to depend on the VARVAL function.
Motions should only be functions of TIME.
WARNING: MOTION MODEL_1.MOTION_4 has been declared to depend on the VARVAL function.
Motions should only be functions of TIME.
这个警告。还有就是SOLVER求解器明明我都选择FORTRAN 但是也提示不能适用C++。这是为什么呢？
