Dear all,
Greetings of the day.
The values that are defined under "density" & "Elasticity modulus" in the Guccione-active example in ustruct, are they some normalized values or actual values in some unit system? I didn't understand the comment "used for computing tauM/tauC".
Also can you please explain why these values are different in the "struct formulation" of example related to cardiac mechanics in documentation of simCardio ?
Looking forward to your kind support.
Warm Regards
Dipankul

Re: Doubt in "density" & "Elasticity Modulus" used in Cardiac Simulation
Dear Dipankul,
tauM and tauC denote the stabilisation parameters in the Variable Multiscale method (VMS) formulation used in the ustruct module.
Elastic modulus is used to calculate mu and c which is further used to calculate tauM and tauC.
Whereas the struct module doesn't need this.
Brief detail about the formulation is given on the website https://simvascular.github.io/docsSimCa ... ics-theory
A small screenshot of the same I am attaching here.
.
The subroutine for the calculation of the stabilisation parameters in the code can be found at svFSI/Code/Surce/svFSI/MATMODELS.f (line 1095 to 1125)
Also for further details regarding the VMS formulation, you can refer to the following paper.

Hope this is useful,
Cheers
