Re: Post processing with command line in linux

Hi Yikai, Thank you for your question! You certainly can run svpost from the command line. You can check the input arguments by running svpost with the '-h' flag. But briefly, you will likely want to include the following flags: -start X: starting step number for post-processing -stop Y: last step n...

Re: svpre does not work

Hi Dai, One way you can check your mesh is right-clicking the mesh from the Data Manager and clicking the option to "Export Mesh-complete". This will produce a folder that has your mesh information that you can check in Paraview. The "mesh-complete.mesh.vtu" contains your tetrahedral volumetric mesh...

Re: A question about solver.inp file

Hi Akash,

That is great news! Glad you got it working. Those ASCII character bugs are a pain to debug, and often the last thing I think about!

Re: svpre does not work

Hi Dai,

Thank you for your question! It is a little hard to diagnose without some more details. Can you confirm that your model was properly meshed and all surfaces were assigned boundary conditions?

Re: Comparing results computed in 3d models in 2 different meshes/points in paraview

Hi Sajeda, Glad that helped! Measuring the length of a path is difficult. I usually accomplish this task using Python VTK scripts. Measuring the area of inlets and outlets is built into SimVascular! If you click and highlight a face in the Modeling tab, on the bottom right of the screen you should s...

Re: Can't mesh clinicalcase2

Hi Ruiyi, Sorry for the late response! I have been busy with other tasks lately and have not been able to get on the forums much to answer questions. I can happily confirm that the presolver completed successfully, despite the FATAL ERROR. The reason that message pops up is that we use a fairly old ...

Re: A question about solver.inp file

Hi Akash, In the solver.inp file, there is a command called "Surface ID's for Force calculation". Here, you can specify which surfaces you want wall shear stress calculations. The default setting is to specify the entire exterior surface of the domain for force calculation (i.e. surface ID 1). Hope ...

Re: How do we scale the 'non-linear residual'?

Hi Sudharsan, Thank you for the question! As you mentioned, the non-linear residual represents the error in the velocity and pressure fields. It is computed by plugging in the current solution for velocity and pressure into the Navier-Stokes equations (which should equal zero for a perfect solution)...

Re: Comparing results computed in 3d models in 2 different meshes/points in paraview

Hi Sajeda, I think it is likely you are viewing the magnitude of the vWSS vector in the line bar. But when you hover over the points, you are looking at the (x,y,z) coordinates of the vWSS vector. One way to display the magnitude of the vWSS in hover points is to create a new array which computes th...

Re: Question on installation in redhat system

Hi Luning, Thank you for your question and interest in SimVascular! We hope that it will serve your needs. Are you looking to install the entire front-end GUI on your redhat system? Or just the flowsolver? In either case, since the .deb file is not working then we recommend that you compile the code...
