Hi all I am doing a simulation about the aortic dissection.I followed the manual step by step to import the neo-hookean into my model.Now I thinked I completed it. But I'm still confused, I just know how to turn on the neo-hookean in Elmer, I don't know what the neo-hookean looks like in my model, w...

Hi all I am struggling with the Artery flow.I wanted to study it from the case（ElmerTutorials_nonGUI—> Tutorial 11—>Blood ejection from a ventricle into arota）. I followed the manual step by step,imported the command (ElmerGrid 1 2 contra),and checked the contra.sif if it is the same as manual.After...

Dear peter Thank you very much for your reply. I have added a MeshSolver to my model. But when I finished the calculation, I could only see the changes in the entrance and exit. The changes of blood flow in the vessels were basically invisible. I am also trying to add Neo-Hookean equations to my own...

Dear all. I did a simulation about the FSI in the artery.After the calculation,when I open the .vtu files in openfoam but there are only pressure,displacements and velocity.Why there is no mesh regions button ?And I want to get the streamlines of the results, would you like to give me some suggestio...

Hi all I am doing a simulation about the aortic dissection.At this stage, the simulation I made only uses Navier-Stokes and Nonlinear elasticity solver.And now I want to import the neo-hookean into my model.Do you know how to do it ? Can I do this in which part of the software? I have uploaded my si...

Hello. I want to use Elmer to do the Fsi,so I just make a simple arterial model for it. When I setted up the conditions and runned the solver i got some errors. I want to input the flow as the arrays , but it does not work. ELMER SOLVER (v 8.3) STARTED AT: 2019/05/28 15:52:06 ParCommInit: Initialize...

Hello peter,

I find the test case that you reminded.
But I do not konw how to use it.Is there some instructions about it ?

Thank you.

Hello kevinarden.Many thanks. I followed your advice to input the impulses in Elmer. But it does not work.If there something wrong in my operation? I only use the Navier-Stokes and Nonlinear-Elasticty solutions for Fsi. Do I need to add Mesh updates solution? Could you please explain it more specifi...

Hello.I want to use the ELMER to do the fsi about the artery.

Now I have mode a simple model for it and completed the simulation.

I uploaded the sif file.

The next step I want to add the impulses into the input flow.

Could you give me an advice?

Thanks in advance

I have made a simple artery model ,I wanted to use it for fsi in Elmer.

After I setted up the boundry conditions and runned the solver,the result only included the displacement,and in the results of velocity and pressure ,
,nothing happened.I have uploaded some images of it.

Many Thanks in advance.
