Trouble viewing surface stream lines

Using SimScale
1

Hi there,

I’m having trouble viewing the outputs of my simulation. I am using the incompressible CFD software. All I can see is the enclosure, I can not see how my model actually behaves. How do I view the outputs without the enclosure? Perhaps I am doing something wrong with setting up my simulation.

I would really appreciate your help.

Kind regards,

Can you share the project link with us here in the thread? :slight_smile: Will help you out then!

Best,

Hi!

I had a look at your project and the boundary conditions look unusual to me. For instance, the velocity inlet is being applied in a direction tangent to the side wall:

Could you tell us a little more about this application? Maybe we can propose more fitting BCs afterward.

I’ll also post some links which will probably be useful:

Cheers

Hi

I followed the tutorial and tried running the simulation again. However, I am running into the same problem. I changed the boundary conditions as suggested and followed the tutorial step by step.

Application: I am trying to determine the forces, bending moment, and stresses acting on the model in that at high speeds.

Here is the link to the new simulation: https://www.simscale.com/workbench/?pid=253181473203790855&mi=spec%3A5b8a6414-c4c1-4d13-b783-ffda7e1bcb96%2Cservice%3ASIMULATION%2Cstrategy%3A323

Thanks!
