Streamlines in EnSight using MRI data

Hello,

I am using EnSight to post-process phase contrast MRI data of flow through arteries. I am able to compute the flow rate accurately in each branch using cut planes and obtain mass conservation. However, I am unable to generate streamlines from the main artery through the branches, since the streamlines stop prematurely after a short distance. Increasing the 'Total time limit' does not improve the results. Please see the images below.

Can anyone help with this please.

Thank you,

Gavin

    Hi Gavin,

    Couple of quick questions:

    • Do you have more than one fluid cell-zones in your model?
    • Since this is a transient simulation, I am assuming that you are running a particle tracking model? Did you make sure to write the data is written for all time-steps? You should be able to check this from your folder where you are reading your ensight files from.

    Best,

     Hello,

    I'm also using Ensight to post-process MRI data, and I need to import 4D flow MRI data which is in DICOM format into Ensight. However, I have no idea about this.

    Would you mind sharing that how to get the flow data from MRI?

    Thanks,

    Ming

    I'll lock this as you've reposted (new threads are always better).
