Hi, 1. The parameters for the 3D geometry can be a resistor or an rcr or several LPMs. For example, you want to create an LPM surrogate for a 3D bifurcation model, you can choose to use 3 resistors to represent the three segments or use 2 resistors or 2 RCR models in parallel to represent the 3D mo...

When you use lumped parameter models (LPMs) to represent your 3D simulations, you have two parts: 1 the LPM for the 3D geometry 2. the LPM for the distal coronary arteries which is kept the same as the outflow BCs used in the 3D simulations. You want to identify the parameters for the 2 part to hav...

Hi David, Thank you so much for your kind reply! I double checked the parameters, however, I still get confused. As for pulsatile flow, the whole R of aorta cap should be 139.97/0.09 = 1555; while the steady flow has the setting of 1492. And for the steay flow the R ratio between the aorta and whole...

Hi every guy, I tried the steady flow files in the tutorial coronary normal. However, its parameter setting really confuses me: 1, all the outlets are set as "Resistance." my question: could "RCR" and "Coronary" be set for the outlets in steady flow simulation? 2, the calculation of the "Resistance"...

A quick updating:
I found if I use 'Resistance' for outlet boundaries, the simulaiton can run. However, if 'RCR' is used, the simulation has the error.
Thanks!

Hi, I am using lastest SimVascular on Windows. I tried to run the tutorial model of 1D simulation. However, it gives the errors: 337.52 [sv4guiROMSimulationPython::GenerateSolverInput] A solver input file has been successfully generated. Number of segments: 3 Number of nodes: 9 Number of elements: 6...

It's really a good tutorial.
I highly recommend every new user of simva to do it from beginning to end. Don't skip any step or detail.
I add two more LAD branches compared to the tutorial.
Thanks again for the simva team!

Hi,
I recalculate the cardicac output, using the "area under the curve", and the result is 91.55ml/s instead of 90.7 ml/s. The 90.7ml/s Luca got is calculated by averaging of the flow curves. But I think "area under the curve" should be more accurate.
Any comments are so appreciated!

For my own consistency, I kept using 125000 dyne/cm2.
Thanks for all!

I re-ran the simluation, and now it's good.
I think I did some mistake before.

Here is my current results.
Thanks to all!
