Hi Dr Dalyo, I am working on a 2-way Fluid structure interaction project related to RBC in capillaries. I have designed a micro-scale shell RBC and a fluid medium which has diameter just above the dia of RBC. In the transient structural analysis I have defined two fluid surface interfaces: 1. Exterior portion of RBC 2. Interior portion of RBC. In the Fluent medium I have defined the walls, boundaries of capillary tube and cytoplasm (hollow portion of RBC) which are supposed to interact with with the solid RBC in Transient. I have assumed that blood runs at x velocity and cytoplasm relatively at 0.97x velocity. Similarly, in transient I have 0.97x velocity, 9.7x displacement to Solid RBC When I run the analysis by coupling both systems I receive error by doing so. But if I reduce the time step (0.0004) sec for 10 sub-steps ,velocity to 0.0000097x and displacement by 0.000097x solution runs smoothly. Irrespective of correctness of result, Could yo please tell me why is that if i decrease the velocity, displacement and time steps there is result and why if i consider real time scenario this does not work? Thanks

Hello my question was how can I model a rotating cylinder in a fluid flow. lets say the same case in the tutorial video but with a rotating cylinder. As mentioned in researches rotation effects significantly the vortex shedding activity behind the cylinder. How can I achieve this case numerically? Thank you
@drdalyo9 жыл бұрын
+Oula Fatla Ok! so say using the same tutorial as above, go into fluent, on the left choose "Boundary Condition", then choose "cylinder", then "edit". In the Wall menu, under wall motion, select "Moving Wall". Then set the motion to Rotational, and choose your speed, say "200 rad/s" and click ok. Reinitialize and view the results. For more accurate results, you can change the viscous model instead of laminar to k-epsilon. Let me know how it goes. If it answered your question please subscribe and like! Thanks!
