Post Processing Viscous Forces

[uwmidsun]

Hi everybody,

So I’m familiar with taking SimScale CFD simulations and outputting the results to paraview to be post processed to find the pressure drag, but has anyone had any luck taking those results and finding the viscous drag as well?

I’m interested in this because we create an extremely streamlined body that has a major component of drag being viscous.

Thank you!

Hi @uwmidsun,

This post might be handy:

Drag Coefficient result?

Hi , I am trying to find the drag coefficient for a body, however when I set up a result control I get one value, but when I go into para view and do calculations though there I get another value. I get a much lower drag coefficient in para view, then in the result control, so my question is how is Simscale calculating the drag coefficient? In ParaView I use this equation for drag coefficient : Cd = D / (A * .5 * r * V^2) where D, drag is in newtons, A is reference in meters, r is densit…

Let me know if you need more.

best,
Darren

Thank you so much for this. I was into this issue and tired to tinker around to check if its possible but couldnt get it done. Now that i have seen the way you did it, thanks guys
