how to change to fixed step or variable step in adams/car

[behnam jafari]

hi

I am co-simulating Adams/car and Simulink and in the Simulink i'd like to change the solver to fixed step while running the simulation because my Simulink model runs better with fixed step solver.

the Adams/car solver is usually set to variable step while co-Simulating in Simulink .

1- but can I change it to fixed step ?

and another question :

2- is the solver that we use in Adams/car , important to the solving process in Matlab/Simulink while co-simulating ( for example if I use HHT instead of GSTIFF )?

thanks a lot
