Disable domain box for external flow cfd

[Lemlurker]

i would like to view my flow simulation from outside the domain that was rendered as it is an external vflow

Hi @Lemlurker,

Simulated wind tunnel issues

I’ve made a simulated wind tunnel following a youtube video on the process but I’m having two issues with the post-processor. Firstly I cannot hide the box that’s around the object I created and second I cannot find the different options of what I want to examine (pressure, velocity, etc). Here’s a link to my project https://www.simscale.com/workbench/?pid=108427564136304193

Cheers,
Anna

thanks that helped alot but a couple of things on the back of that, once ive set it to an external view my streme lines are no longer visible, is this because they only work inside a mesh? also is it possibile to output values such as drag coefficent and drag forces? only i cant see the data anywhere

Hi @Lemlurker,

What I do is right click the results and ‘add results to the viewer’ then you get two identical solutions. Hide the external mesh for one (thus leaving whatever it is in the middle visible) and then add the streamlines to the other solution. Is that what you want to do? so it will look like the streamlines are actually moving around the object within.

Force coefficients and forces need to be added as a result control item before the simulation is run. You will need to select the faces in which to apply the calculation. For example, if working with an aerofoil then selecting upper and lower surfaces.

Hope this helps,
Darren
