Hi SimVascularers, I try to install and run SimVascular on Ubuntu via command line. After installation, I have a problem to launch the software. The information is listed below. Could you give me some advice how to solve the problem. Thank you so much for your great help. OS: Linux 4.18.0-16-generic...

Dear Weiguang, Thanks for your reply. Yes, you got it correctly. I get BCs (e.g. pressure) from a 0-D model that I have previously built. Now, I need to link those BCs to my CFD model using a RLC model. I will also try the built-in RCR of SimVascular. I would appreciate it if you let me know of any ...

Hi Atefeh,

Yes, you got it right. I suggest you first smooth your model before import it to SimVascular (e.g. using OpenFlipper) as well as after you import it to SimVasclar using the options available under Models/Local Ops.

Thanks,
Amirtaha

Hi Atefeh,

This sometimes happen to me because of a bad mesh. Maybe you need some smoothing or a different mesh size (sometimes slightly different). Hope it helps.

Hi Nathan, Thanks! Then can you please help me to understand something about the BCs available in SimVascular. First let me explain my problem statement. I have a geometry that was extracted from CT scans. I have the inlet flow rate and pressure profiles. But I don't have the outlet BCs. However, I ...

Hi SimVascularers,

I am wondering if there is a way to apply RLC BCs to the flow outlets. I see that there are different BC options available including prescribed velocity, resistance, RCR, and coronary. Is there a way that we can define inertance at the outlets?

Thanks,
Amirtaha

Dear Nathan,

I am just confirming that I followed the instruction and everything went okay.

Thanks again,
Amirtaha

Dear Nathan, Thanks! I had the version from Nov 2018 installed on my Windows 10 machine. I did not uninstall that version. I just installed the recently released version (assuming that it will also take care of removing/modifying the old version). Then I just simply ran the SimVascular as I used to ...

Dear SimVascularers! I just installed the last version of the SimVascular released this week and the GUI looks like completely different than before. Before I switch back to the previous version (which looked like nicer and more user friendly), I wanted to check if I have intsalled the correct versi...

Hi David, Thank you for sharing that paper. Their conclusion about the outcome of Newtonian and non-Newtonian models for an aneurysm CFD study is interesting. Looking forward to seeing non-Newtonian feature in SimVascular tho since users are mostly researchers who are interested in studying blood (a...
