Re: Simulation stamp does not match

Hi David, the focus of my question was about the restart , specifically. Why did it cause such peaks in the pressure and flow profiles (see red box on the plot)? The peaks wouldn't have been created if I hadn't stopped the simulation with "STOP_SIM" (I did a test on that). And secondly, I am using t...

Re: Simulation stamp does not match

Hello! May I ask a semi-related question? Is it normal for the solvers from svFSI to struggle with convergence (see the lsIt column) during the first timesteps immediately after a restart? Also, is it common for the pressures and flows in the "B_FS_....txt" files to exhibit sudden, strange peaks and...

Re: Simulation using a Stent

Is it then possible to simulate within svFSI three or more components, such as a plaque within the vessel wall (or a stent), in addition to the fluid and the wall itself? I have created a preliminary mesh with three components (fluid+wall+plaque) and an input file. But before further assessments I w...

Re: HGO material parameters

Ok, so there are only the abovementioned ones :) thanks

One last little question:
How are the "Def_Grad" array components saved? ( in struct simulations results for example)
Just to make sure the corresponding components are linked to the right array positions
(see figure)

Thank you!

Re: HGO material parameters

Thank you really much! :) Another thing: is there a way in svFSI to set (some or all) the solver parameters available in svsolver (see figure)? For example Residual criteria, residual control, step construction, ... as far as I know, the available settings are: Add equation: FSI { Coupled: ... Min i...

Re: Automating Batch Simulations

Is there a way to "gently" interrupt a rigid wall simulation launched from terminal (svSolver)? as the command "touch n-proc/STOP_SIM" for svFSI does. Because sometimes my simulation get stuck due to failed connection between processors I think (see figure) and I usually press "Ctrl+C" to end the pr...

HGO material parameters

Hello everyone, i wanted to have a feedback on HGO (decoupled) material parameter settings: As I set: HGO-{ a4: / b4: / a6: / b6: kappa: (k=0) } Is the parameter mu appearing in the formulation (see figure) derived from "Elasticity modulus" (E) and "Poisson ratio" keywords so that mu=E/(2*(1+poisson...

Re: FSI - two Boundary Layers

Thank you David! Sorry for the delay, Exactly, that's why i was triying to import the mesh as a new model! As suggested here (https://simvascular.github.io/docssvFSI.html#app_fluid_mesh) if you import the ".vtp" file extracted from the solid mesh and use it to generate the new volume mesh (of the fl...

FSI - two Boundary Layers

Hi everyone, I'm wondering if it's possible to mesh the fluid domain in an FSI mesh with a boundary layer, after creating the solid wall (using Boundary layer as an extrusion method in the first place) - see "img1.png" I'll explain myself better: 1) create the solid mesh by extruding outward the sur...
