Can you check if the inflow BC is correctly imposed? It seems there is no pulsatile flow in the model. Make sure you have the same svpre command for the inlet as that used in the rigid case. You can also compare the bct.dat files that prescribe the inlet velocities. The bct.dat files should be the s...

Is this pressure an outlet pressure with an RCR boundary condition? If so, it is likely that the gradual increase in pressure is caused by a relatively large RC constant. If I remember correctly, the RCR analytical solution includes a term for initial conditions, which decays as exp(-t/(C*Rd)). If C...

If the wall faces for the stent and aneurysm are separated, you can directly assign different wall properties in the pre solver script.

Assuming that the coronary circuit is parallel to the systemic circuit, P/Rcor=P/Rsystem *4/96. Therefore Rcor is ~ 24Rsystem. Yes, you can estimate the LCX resistance in this way. This is just an initial approximation. You need to adjust the values to achieve a desired flow split.

Usually, if the simulation is converged under steady flow conditions after n steps, the result for the last step is supposed to be "the same" as that for n+1. However, unsteadiness can exist even if the inflow condition is steady. For example, fluctuations in pressures and velocities can be created ...

I can find my results (proc-$numprocs.czf.tar.gz) in Storage->experiment name->ARCHIVE, If the results are not generated, can you share your files so I can take a look?

Sorry about that. The input option for user.f was somehow lost when I made some changes. I added it back. Could you please try again? I tested a cylinder with GenBC. It seems to work.

I created a new application for genbc. Can you try it?
Thx

The aneurysm is missing in your walls_combined.vtp. If you use walls_combined.vtp to set up no-slip boundary condition in your svpre file, the aneurysm wall won't be included resulting in non-zero velocities on that part. You probably need to retag the aneurysm face as wall_aneurysm and remesh the m...

If you already ran the simulation for at least 1 cycle, you can generate the flow and pressure curves for each face (see Postprocessing Calculate Flows in the tutorial). Plot the inflow curve and see if it agrees well with your input waveform.
