Looks like a newbee problem, but if someone can help me to understand my mistake?
welcome to the forum. As a start to cfd-workbench, please have a look at the turorials
from the developers (Dr.Oliver Oxtoby).
After importing the stl in FC, please check if the body is a full watertight solid.
Goto "Mesh Design"-wb, Meshes==>Analyse==>Check solid mesh
If it is a solid, you must convert the stl to a "body" in the part-wb with "Create shape from Mesh".
Thats the body you can mesh. If your body isnt a solid, you must repair it. I use netfabb-basic for this.
On the pics you see a windtunnel with a prop. The prop in the tunnel was designed with FC and has 13 faces.
No problem to adress the BC-conditions. I exported the prop as an stl, then reimporting the stl. After converting
the stl to a body, you can see that the body has 1458 faces! It is impossible to adress the BC by clicking every face.
Thats the Problem when using stls in FC for FEM/CFD...
I have installed the 2016-1 version month ago without using the preferences option. Which version do u have
installed via preferences as a default (2016-1/2016-2/2017-1?)
@Mx74: can you post a screenshot of your simulation?
Here is a result with a fixed prop.
Challenge: how to setup a rotating prop with dynamic mesh?
