Unicorn

Incorrect Cd value

Asked by Rishik Ranjan

Hi,

I installed unicorn hpc 0.1.2.
I ran the 'cube' example present in icns folder on a single machine (pc).
However, I am facing a problem.

In the iter_0 folder,

-- The Cd = 2F (as read from aero_f.dat) value is coming out to be negative after 10~12 time steps. In fact it never recovers after that and only tends to zero.

Please tell me how can I rectify this.

You have to run more adaptive iterations. It's expected that Cd is way off (even negative) after the first iteration.

Can you help with this problem?
