LS-DYNA ICFD Windkessel type boundary condition

BWLi

Hi Community,

I am using LS-DYNA ICFD *ICFD_BOUNDARY_WINDKESSEL model to prescribe the outlet pres. conditions to the branches of my vessel geometry. Anyone knows how the pressure is calculated from the circuit? Does ICFD automatically retrieve the flux and pres. from the prev. iteration to calculate the current pres. on the surface?

I compared the model deployed in ICFD with a prev. in-house model in CFX, ith the same geometry and BCs, yet the solutions are very different. I consulted the user mannual, but unfortunately the description was quite vague...

Thanks.
