how to transfer scalar data from Mesh A to Mesh B

ParaView Support

Hello dear paraview users,
i was wondering if it is possible to transfer or interpolate a scalar data from a Mesh A to a different Mesh B?
Knowing that Mesh A and B have the same geometry… but different meshgrid!
My data is stored in data.vtu (i got it from a Elmer FEA software. My scalar is the temperature for example ). My meshed were made with GMSG and these are called MeshA.msh and MeshB.msh.
I hope that my question is clear? and that there is a solution under Paraview :wink:
Cheers

Hi Sebastien,
You’ll have to use the Programmable Filter
Here is a ParaView state file that transfers the Normals from a cube looking superquadric to a sphere looking superquadric.

transfer-scalar.pvsm (498 KB)

For your case, since you want to potentially interpolate values from a mesh to another, you can use Resample With DataSet filter. The filter allows you to choose the dataset providing the Source Data Arrays and the other providing the Destination Mesh.

Thank you very much for your solution… i’m gonna test it as soon as possible.

Thank you very much for your reply.

I noticed this option “resample with data set” but did not really understood how to use it and i did not find any tutos or example so far!

i will investigate it surely. I m not a paraview expert, i only use it to visualize data and export some data but i never used the filter capabilities!

Cheers

Thank you for posting this. I’ve been trying to append a small part of dataset B to dataset A, trying to make dataset A’s mesh the same as B’s, but it never worked. Resample With Dataset solved this for me.
