ok sir from next time i will use appropriate forum

DOF decreased means when we use the model reduction methods it will reduce the degrees of freedom from high to finite.

For example chassis , whole vehicle

@LOKESH KATARI

DOFs are depended on element numbers/types.

quad shell first order has 4 points and 6 dofs on every point=24 DOFs.

If you create full vehicle model which contains 100.000 points (only shell elements and beams) you will have 6*100.000 DOFs

if you separete chassis from full model and it will include only 50.000 points you can estimate your reduction coefficient=)

Usually, total degrees of freedom will be written in the .out file. You can use remove the constrain dofs from the total... I guess this will help?
