Dear all,

this is my first post. I am new to OpenFOAM (this is just my second project) and I just started my last master project. It is about the simulation of fluid inside the Left Ventricle starting from velocity data collected with MRI. The first step is to extract the 3D model of the ventricle, run the simulation and validate the model with the velocity data from MRI.
Now I need to import the Boundary Conditions; because of the manual extraction of the volume (the LV contours have been drawn manually on MR images) I have a boundary surface with velocity not equal zero. I created a STL file for the boundary surface in matlab, and I also extracted the velocity data on the boundary always with matlab. Now I would like to import the STL file and create the mesh using snappyHexMesh, then set the velocity data as boundary condition using uniformFixedValue with a csv file (created in matlab).
My question is: How do I have to structure the csv file? I would like to have something like:
(x1 y1 z1 u1 v1 z1)
(x2 y2 z2 u2 v2 z2)
...
for each node of the stl file. But I am not sure if this will remain consistent also after using snappyHexMesh.

Thank you very much!
Best,
