Re: Importing complete mesh for simulation

Thank you Dave! I am able to import my mesh now without issue. Now,with my .stl imported as the "model", I would then need to generate a volumetric mesh within SimVascular using TetGen under the "SV Meshing" utility. My issue is that I need to use a specific volumetric mesh for my simulations in Sim...

Importing complete mesh for simulation

Hello, I am trying to import a .stl or .vtk file into SimVascular to run a fluid simulation. When importing, it important the I retain the original geometry because I need to have a one-to-one correspondence between these simulation results and results simulated through other means, on the same mesh...

Re: Automating Batch Simulations

Hi Dan, A weakly prescribed pressure boundary condition means that the pressure is not proscribed at the nodes but constrained to equal the integral of pressure over the outlet face is referred to as the weak form. The boundary conditions are given using a lumped parameter model but the non-linear ...

Re: Automating Batch Simulations

Hi, I've got the pipeline all set up and am able to run large batches of simulations! It takes me roughly 1 day to run 1000 simulations on our linux server. Currently I am using the coronary model from the SimVascular website. I am modeling the system in the simplest way possible - steady inlet flow...

Re: Automating Batch Simulations

Hi Dan, Having both OpenMPI and MPICH installed does indeed cause problems. Thanks for posting the solution! I've created a program to compute the average flow files here https://github.com/ktbolt/cardiovascular/tree/master/create-flow-files. Let me know if this works for you. Cheers, Dave Dave, I ...

Re: Automating Batch Simulations

Shannen, I dont know if this might help, but I was having issues due to the version of MPI called by my linux system when using the "mpiexec" command. Beyond the "which mpiexec" command, some of the following might help. In my case, my system was using openmpi. I found this out with the following co...

Re: Automating Batch Simulations

Hi Dave, Perfect, this is exactly what I have been looking for!! Coincidentally the only parameters I am really interested in are the average pressure and flows from the all_results-averages-from_cm-to-mmHg-L_per_min.txt file. Any help on generating these numbers would be much appreciated. Thanks! Dan

Re: Automating Batch Simulations

Thanks for the reply Dave! I was looking into generating the solver.inp and sim.svpre files. It looks like the only input to the svPre is the sim.svpre file, and the outputs are (bct.dat, geombc.dat.1, restart.0.1, numstart.dat)? I am assuming I would then generate the solver.inp file and copy over ...

Re: How to see console output on Mac

You can call svSolver in terminal and see the step-by-step output. First set the current directory to the folder containing the restart files: cd [restart file path] Then call the svSolver executable: mpiexec -n [number of processes] [solver path]/svsolver For example, I input the following in termi...
