Re: svFSI results file structure

Hi Dave, Yes I believe we are building svFSI from source. I had set my output options to the values I showed in my first post, and at the end of the simulation I end up with: stFile_XXX.bin for each timestep computed result_XXX.vtu starting with timestep 200 B_NS_Energy_flux_flux.txt B_NS_Pressure_a...

svFSI results file structure

Hello, I am running a transient svFSI simulation via command line on our linux cluster, and I'm trying to figure out which options to select in the input file to get the results I need outputted. I am more familiar with svSolver, which automatically generates restart files that I then convert to sin...

Re: Not all results converted

Hi Dave, These simulations are currently running on my Ubuntu 18.04 laptop using 6 cores. The simulation runs to completion, and most variables (pressure, velocity, timeDeriv, etc.) convert successfully for all time steps. It seems that maybe the results that take some post-processing computation (r...

Not all results converted

I'm using the Python API to run a series of simulations with svSolver. As part of this routine, I use the svpost command within python: sub.run(["/usr/local/sv/svsolver/2019-02-07/svpost", "-all", "-start", str(s1), "-stop", str(s2), "-incr", str(sinc), "-indir", "./"+nprocDir+"/", "-outdir", "./", ...

Re: Automating Batch Simulations

Dan, Thank you for that suggestion! I ran the commands to see more about my MPI version and I have the same situation as you, OpenRTE and then a list of several mpiexec versions. In the GUI, I point Simvascular to use the /usr/bin/mpiexec.mpich, so it makes sense that I need to tell it to do that wh...

Re: Automating Batch Simulations

Hi Dave, Thank you for your patience while troubleshooting these errors with me. I'm running Ubuntu 18.04.5 LTS, 64 bit. My output for which mpiexec is: /usr/bin/mpiexec Could I be missing any supporting libraries that help svsolver to communicate with MPI? Do you think that writing restarts for eve...

Re: Automating Batch Simulations

Dave, I am running the simulations on my personal computer, but I have been using mpiexec to run the code due to issues with the non-mpi solver discussed in a previous thread. How does svpost detect how many processors were used to run a job? Do I need to specify something about the number of proces...

Re: Automating Batch Simulations

Hi Dave, Thanks, now I'm able to make the results convert to a single file! I want to be able to plot pressure vs. time for a periodic flow simulation, so I need data at small time increments to create the full curve without losing much information. Another issue I'm encountering with svpost is that...

Re: Automating Batch Simulations

I have another quick question about using svpost : How do you achieve the "As Single File" option to create only one VTP and one VTU for all of the selected steps in the simulation? I tried using -vtkcombo based on its description, but that instead created one VTU for each step. If I'm running hundr...

Re: Working with New Python API

Dave, Thank you for this solution! Things seem to be running smoothly with the new code. Eric, Thank you for sharing all of these scripts and for offering specific suggestions for my project. Regarding the mesh failure errors, I found that changing the use_center option: sv.vmtk.cap(surface=loft_sur...
