Dear All,

I am trying to work with FSI simulation of Blood-flow in an artery using a coupling of the Laminar Fluid flow and the Solid Mechanics Interface.But my solution-progress is stuck around 10% ( at the time step value 0.1) since some hours now.I have tried to do the same study after changing the time step increment but so far no results.

I have also tried to solve the same problem using the FSI Module of COMSOL but when executed,it gives an error 'Segregated solver steps do not involve all components.' [attached file :FSI_interface_2D_bloodflow.mph]


I appreciate any help or suggestions.

Regards,

Irfan.

Did u find a solution to this problem?
I am getting the same error inspite of including all the components. I get this error when I run the file on a cluster.

Hi

often you can check the segregated solver steps, and identify which dependent variable is left out, and add it manually. The question to ask, and give an answer, is in which step should the dependent variable be integrated into

Good luck
