Hi everybody,
i am failing to reproduce the FSI cylinder tutorial. Meshing and assigning BCs all works as far as i can tell.
So i would be very happy if someone could help me. Attached please find the configuration files.

The error i am getting reads:

Code: Select all

 ----------------------------------------------

    SimVascular Fluid-Structure Interaction
                  (svFSI v8)

 ----------------------------------------------

 This program comes with ABSOLUTELY NO WARRANTY
 Compiled on 10-18-2018

 Running sequentially
 Number of meshes: 2
 Reading mesh <cylinderMesh-mesh-complete_domain-1>
 <VTK XML Parser> Loading file <cylinderMesh-mesh-complete_domain-1/mesh-complete.mesh.vtu>
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ERROR occured, see below for more explanation
ERROR: Unable to identify combination of nsd and eNoN
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks in advance.

Hi D. Rast,

The error you are getting means that the mesh file you created is not valid: nsd = number of space dimensions, eNoN = the number of nodes per element. If you visualize the cylinder-mesh-complete_domain-1/mesh-complete.mesh.vtu file you will see that it is not a volume mesh. There is a bug in SimVascular when it writes out the .vtu files. I am working on a fix now.

Cheers,
Dave
