[Paraview] Paraview 5.1 Parallel & Delaunay

Thu Jul 21 03:17:25 EDT 2016

Hello Stephane,

The STWCS requires that your seeding data is available on all processes, the solution to your problem is in the attached email. You must simply save your masked points as a VTM file and read it before invoking the STWCS filter. Regarding the issues with the Ensight reader in parallel (second attachment) there was no progress on the Paraview side I assume.

Regards,
Lukasz

Subject: [Paraview] Paraview 5.1 Parallel & Delaunay

Hello,

I would like to report a few problems encountered on Paraview 5.1.
I am running the Binary-MPI version on Win7, on a workstation with 32 threads (16 physical cores right?).
When running in Parallel with Ensight data, I am using the same workstation as both Server and client:

- I can execute the pvserver (mpiexec -n 4 pvserver) up to n =24 without problem
- From there on the same machine I launch a paraview session and connect to the server
- I Can launch the geometry without problem

The problem occurs when I load the D3 filter on the geometry  with n>12. I get an error message. This problem was already reported on March 18th, 2016 by another user.

If I stick to 12 cores or less I get another problem with the following workflow:
I want to apply the StreamTracerWithCustomSource (STWCS) in Parallel so I do the following:

1) Save the Source surface as a *vtm file, and read it back in current session
2) Apply D3 filter to Full model
3) Apply STWCS filter with D3 filter as input and *vtm surface as source.

this workflow works perfectly, but there are too many seeds so after step2:
3')Apply MaskPoints to *vtm surface
4)Apply STWCS filter with D3 filter as input and result of MaskPoints as source ==> Paraview Crashes in Parallel (This works well in a non-parallel session)

Finally a question on Delaunay2D

I have a point clouds extracted from a surface with a big hole in the middle. Applying Delaunay2d Always closes the hole. is there a way to keep the hole ?

Thanks in advance.
