~Error: Mesh kernel not available/SV Crashing

[Bradford Thorne]

Hi,
I am trying to finish meshing a model using Version 2.0.10320 for Mac but SimVascular either crashes or outputs 'Error: Mesh kernel not available' when I try to run the mesher after warning me that it will take a while to execute. I have tried using both MeshSim and TetGem but both yield similar results. I believe all of my dependencies are installed, so I'm not sure where to look for the kernel or what the root cause is.

Thanks!
Bradford

Below is one of the outputted error messages:

Mesh kernel is not available

Hi Bradford,

Is SimVascular outputting this error message and then crashing? Or is it just outputting this error message and then not meshing?

I just ran a couple of tests and using this version on Mac, I was able to mesh with TetGen on a couple of different test computers.

Can you make sure you have done a few things before trying to run the mesh:
1. Set your project directory under File->Select Project Directory
2. Load the desired solid model under TetGen->Mesh Options->Select Solid Model.
3. Prescribe a mesh edge size that makes sense for your model

Last thing, you will not be able to mesh with MeshSim on Mac and you should get the error you described. Only TetGen is available for meshing on Mac.

Thanks!
