Just asking

No, you are not just asking.

You are trying to infer something that simply is not present in my post.

Parametric study is the commonly accepted practice when we want to determine the affect of one parameter on a system. "We" refers to those who are formally trained in applied physics.

Like I said, you will do quite a bit of parametric study when you deal with aerodynamics whether that is in the classroom or as a member of a design team.

Simply put, there is no way one can have any amount of formal training in applied physics and not understand the value of parametric study.

You will fail the classes if you cannot answer questions about the cause, affect, and significance. On a design team, you will cost money, time, and possibly lives.

Mr Hari Pihl would earn a big fat "F" for the semester in any class on this subject I ever took or a trip to the unemployment line.

All the best,

Crumpp
