Hello Everybody,
i try to simulate different impeller geometrys and analyse the different resulting fluid velocities.
Therefor i started based on this comsol blog entry:
www.comsol.com/blogs/deformed-...tions-and-linear-translations/
After that i added a Fluid-structure interaction physic node, but i keep getting the error-message:
"Failed to find consistent initial values.
Segregated Step 1
Undefidned variable.
Variable:comp1.fsi.K stress tensor testXY, Geometry: geom1, Boundaries:3,4,6,7
[..]"
But i don't know what to add or what boundary condition is wrongly applied.
This blog entry:
www.comsol.com/blogs/how-to-im...paddle-stroke-with-simulation/
It shows almost what i want to figure out. But i just need the rotating "paddle"
Could you have a look?
thank you and kind regards
Jan
