Hi.. I runned icoFsiElasticNonLinULSolidFoam solver through the tutorial case called "HronTurekFsi" ( foam-extend 3.1). I believe that the running is ok, but I could not see the results in PARAVIEW.. typing "./Allrun" and "paraFoam" on the terminal.. see:

the directory folder is this:

inside "solid" folder I have this files:
Screenshot from 2014-07-07 16:05:38.jpg

inside "fluid" folder I have this files:
fluidd.jpg

How can I use paraView to see results?

I found it strange one thing, though not any errors have appeared during the simulation, there was no creation of folders of time instants, only have the folder "0", "constant" and "system"... how to work with this kind of simulation, where I have "fluid" and "solid" folders? My GOAL IS TO SEE THE RESULTS.

tHANKS FOR ATENTION FRIENDS!

Hello steven123,

you must first change into your fluid-directory and then start paraFoam. Then it will work... I hope it will work!

Hello Georg,

at the moment I have the same problem. I want to see the results. I tried your hint and changed the directory gluid before starting paraFoam.
Here you can see my results. But when I want to see the current of the fluid and the movement nothing change. So is there any other thing I have to change or recognize?

Thank you for your help!

best regards,
Stephie

Hello Stephie,

I cannot open your results or the image you wanted to upload. And so far I didn't really understand your question.

What do you mean by movement? The mesh movement? The movement of the fluid?

You said that nothing changes. Did you reconstruct your case?

Cheers Georg

Hello George,

I'm sorry.. I wanted to upload the geometry of the mesh, which shows me in paraView.
Die duration of the simulation should be 40s....and I just can see 1s. So I guess there was a mistake while solving. I try it again and the simulation will run.

But thank you for your hint before

Hello George,

I tried the simulation again, but I have the same mistake like yesterdday. The comutation stops everytime after some minutes. So the simulation goes just one second.
Do you know where the problem might be?

this is the text the terminal shows:

I would be very gratful for your help!

Thank you, best regards,

Hello Stephie,

sorry but this output doesn't really include helpful information.

You should have a look into the stdout and stderr of icoFsiElasticNonLinULSolidFoam. Usally it's all written into a log file, e.g "log.icoFsiElasticNonLinULSolidFoam".

Have fun with the debugging!

Cheers

Hello Dears
i am using this solver for my case.
in the tutorial case of this solver the properties of fluid and solid set to

fluid density = 1 kg/m3 kinemaic viscosity = 10e-3
solid density = 10 kg/m3

what is the meaning of this properties.?
when i set my real properties for blood and vessel

blood density = 1000 kg/m3
vessel density = 1200 kg/m3

my solution crashed by " complex eigenvalue detected for tensor ...." error.

best regards
