[ESPResSo-users] fixing an object in a fluid than only rotates

[Holst, Lena]

Hello,

 

I want to create an sphere object in a couette-flow. The object should only be able to rotate, but fixed at one position. When I set the origin of the object at each integrationstep at the same position, every integration it comes the message “Recalculated forces, so the LB coupling forces are not included in the particle force the first time step.” So, I think this way is not very useful. Is there any other way to fix the object at one defined position, so that this is only able to rotate through the force of the fluid?

 

Best regards and a lot of thanks for effort,

Lena Holst
