Re: Difference between pressure and average pressure

Hi Sajeda,

Your question is a bit vague. Average pressures are calculated over the inlet / outlet faces of the model and are stored in the all_results-pressures.txt file.

Have a look here http://simvascular.github.io/docsFlowSo ... ostprocess

Cheers,

Re: 2D segment error

Hello,

The level set segmentation is not working on Windows. I have filed a GitHub Issue for this problem (https://github.com/SimVascular/SimVascular/issues/456).

Re: svsolver

Hi Gaston,

You are running on a cluster using Slurm?

The exit code 127 can be caused by a couple of things, the svsolver program can't be found (i.e. it is not in your path) or a library that svsolver uses (e.g. blas, lapack) cannot be found.

Cheers,
Dave

Re: Simulation Not Running

Hi Hannah, Sorry for the late reply, had to focus on other things for a bit. I looked at the .svpre file you sent. The problem is that the line set_surface_id_vtp mesh-complete/mesh-surfaces/cap_L Subclavian.vtp 5 contains a space after cap_L. You must have named a segmentation L Subclavian . You sh...

Re: Simulation shows NAN

Hello Dai,

What solver are you using and what OS are you running on?

There might be a problem with your mesh although I think that you would get bad results right away. Try to reduce your time step and see if that helps.

Cheers,
Dave

Re: the levelset button did not respond to the 2D segmentation

Hi Qiying,

You would get this error message if there was no image data loaded into SimVascular. You can load image data by right-clicking on Images and selecting Add/Replace Image.

Re: Simulation Not Running

Hi Hannah, The error you are getting using mpiexec is because you need to specify the number of processors to use when executing the simulation. The mpiexec command to use 4 processors is mpiexec -n 4 /usr/local/sv/svsolver/2019-01-19/svsolver solver.inp The <NPROC> I used in the above message was m...

Re: Non-Newtonian fluid

Hello Dai,

SimVascular does not currently support a non-Newtonian fluid model. We will probably implement one in svFSI in the future but there is not set schedule for that.

Cheers,
