Using the mesh created elsewhere

Hi All,
Would be possible to start the simulation pipeline using the mesh created elsewhere ?
I am attaching a snapshot (some of the itens are not available to choose)

Hello,
There is currently no mesh import capability in SV.
See
viewtopicPhpbb.php?f=188&t=13273&p=38121&start=0&view=.
Cheers,
Dave

The script here
https://github.com/ktbolt/cardiovascula ... vtu/python takes a mesh .vtu file and creates the SV model and mesh files. The .vtu needs to have GlobalNodeID, ModelRegionID and GlobalElementID data arrays defined.
For example, running the script with a file named coarse.vtu
Code: Select all
$ python create-sv-mesh.py coarse.vtu
creates the following files
Code: Select all
coarse-mesh.msh coarse-mesh.vtu coarse-model.vtp
coarse-mesh.vtp coarse-model.mdl coarse.vtu*
You then
1) Create an empty SV project, save and quit
2) Copy the coarse-model.vtp and coarse-model.mdl files to the project's Models director
3) Copy the coarse-mesh.msh, coarse-model.vtp and coarse-mesh.vtu to the project's Meshes directory
4) Start SV and open the project, you will see the Model and Mesh tools with the data from the files
5) Set the model faces to type
cap as needed (by default all faces are of type
wall)
Cheers,
Dave

Hi Dave,
Thanks for the update. I am going to give a try : import mesh in format .msh (ansys fluent) into SIMVASCULAR

Hi Dave,
Would be possible to use the script to a .vtm file ?
Thanks

Hi Alexandre,
I don't know what a .vtm file is. If that is an ACSII format for a mesh then you can create a VTU mesh from that and use it to create SV mesh and model files.
Cheers,
Dave

Hi Dave
.vtm is the format Paraview allow me to save an opened(inside paraview) .msh (ansys fluent mesh file)

Just save to a .vtu file and then add the node and element IDs if needed.
Cheers,

Hi Alexandre,
I don't have any experience with MultiBlock data sets. You will need to use some sort of Paraview extract filter to extract the unstructured grid data and write it.
Cheers,
Dave
