Hello, I am using a custom inlet boundary condition (bct.dat) where the flow at some of the mesh nodes in the inlet plane is positive (i.e. backward flow). My question is if Simvascular treats this modified bct.dat file differently than the inlet boundary conditions with a negative flow (i.e. forwar...

Hi SimVascularers, I am trying to test the potentials of the 1D simulation for our research but I got some warnings and errors as I will describe bellow. The computational domain is an arterial tree with one inlet and 46 outlets. I imported it to SimVascular (i.e. the geometry was not segmented from...

We solved this issue. For those might face the same issue in future:

After uninstalling the driver downloaded from Nvidia website, we installed the driver via apt-get and now sv is working.

Hi David, I would like to provide you more information about our environment. Actually we had sv running fine on this computer before. Then we made the following changes on the computer: Before update: Nvidia K80 Graphic card with the driver v395.xx With that, we could do both GPU computing and sv. ...

Hi David,

Yes, I want to run sv remotely on another computer with Ubuntu 18.

Thanks,
Amirtaha

Hi David, I installed the simvascular and all other stuff that we had discussed in this thread on a Linux machine. Once I run simvascular, I get this error and the software doesn't run. Can you please advise how to get around this? [1.268] [BlueBerry] LOG: Warning: Detected recursive attempt by part...

Hi Hongzhi, Thanks. I followed the way that you suggested. The new simulation stopped at time step 16000 while the simulation is not 100% completed yet. So I suspect we might needed to create files for simulation again. This second simulation started from time step number 8000 and ended at 16000. Ho...

Dear Hongzhi,
Thank you very much for the clarification and procedure. I will follow these steps.

Could you also please confirm if the procedure that I explained in my previous message was correct as well or not.

Thanks,
Amirtaha

Here is what I finally ended up to solve this for anyone who might have the same question in future. 1. Used the "Last step to restart.x.0" to create restart file from the last step of previous simulation. 2. Renamed restart.8000.0 file to restart.0.1 3. Created a new simulation with the additional ...

Dear SimVascularers, After my simulation was done (8000 time steps, time step size: 0.0003), I noticed that I didn't choose enough number of time steps. Actually, I need to run the simulation for at least an extra 9000 time steps to get full 5 cardiac cycles. Since my simulation is computationally e...
