IC Files with Changing Geometries
Posted: Mon May 17, 2021 6:00 am
Hi all,
I was wondering if there is any way to initialise the conditions in a new simulation form the results of a previous simulation that has a slightly different geometry?
I have been changing the geometry of some of the vessels in my model, but each simulation is taking around 12 cardiac cycles to stabilise pressure.
I'd like to save some time for each simulation as the majority of the domain doesn't change between simulations.
I have tried using an IC file as well as replacing the restart.0.1 file for the simulation, but both fail.
I read about a similar method in this paper:
http://link.springer.com/article/10.100 ... 9-3#page-1
"We used 4 Newton-Raphson linearization iterations per time step for all the models. We simulate flow in the first model geometry for 10 cardiac cycles to ensure convergence, and then perform subsequent simulations for other geometries using the first case as the initial condition. Only 3-4 cardiac cycles are subsequently needed for the results to stabalize."
This paper uses a LPN whereas I am using the standard BC options within SV.
Is this still possible to replicate?
Thanks,
Charlie
