Re: questions about the coronary mesh

Hi, Yan I think you need to carry some mesh independence experiments, and verification and validation would be recommended for CFD simulation. There are some practically rules to follow, you may refer to the references below: 1. Overview of CFD Verification and Validation: https://www.grc.nasa.gov/w...

Errors in the "create-flow-files" code

Hi, Dave I'm tring to run several cases in SV by using batch file in Windows 10. Currently the automatic job submission and result export are work well. To export the flow files, I complied your code of "create-flow-files" in Ubuntu shell within Win10 (Ubuntu 18.04 LTS) with no problem, but got "Seg...

Re: Cannot use all CPU cores in dual-CPU system

HI, David! Thank you for the suggestion! Use /affinity instead of /a in the command line would be ok to use all cores without any problem. mpiexec -n CORES /affinity "C:\Program Files\SimVascular\svSolver\2019-05-28\svsolver-msmpi-bin.exe" "YOUR PATH\solver.inp" Best Regards, Guangyu Hi Guangyu, The...

Re: Cannot use all CPU cores in dual-CPU system

Hi, David I'm running on Windows 10. I refered to the solution of previous post (https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=188&t=14168&p=41350&start=0&view=), but seems don't work. Current hardware platform is 2*INTEL XEON 8373C (2*36 cores). There is another dual-cpu workstation in my la...

Cannot use all CPU cores in dual-CPU system

Hi

I'm running SV on a dual-CPU workstation (36 physic cores each, 72 cores in total, HT disabled). However, I can only choose 36 cores when generating the files for simulation. I've tried to use MPI in command line, -n 72, but the CPU work load only hanging around 50%

Re: Failed to finish creating data files

Hi, Korteland! Thanks for the share! I tried to install the fortran runtime, but still got the same error. [ PROBLEM SOVLED ] I installed an older version of SV (2019.08.09) and svSolver (20190528 ), have no problems on data file generation and MPI solving. Hi, I had the same problem and was able to...

Failed to finish creating data files

Hi I'm using the latest version of SimVascular and svSolver, when I'm trying to generate the data files for simulation, the error "Failed to finish creating data files" pops up. There are no details in the "Show details" window. Seems no clue from the mbilog window as well. I've tried generate the f...
