Problem with ElmerGrid partitioning

Post by einatlev »

Hello
I am trying to create mesh partitioning using command line ElmerGrid. It works fine for most of my meshes, except one.
I'm attaching the original gmsh GEO file. I use
ElmerGrid 14 2 Erebus.msh -partition 2 2 1
and then I am getting the following output:
Making a simple partitioning for 1920685 elements in 3-dimensions.
Ordering 1st direction with (1*x + 0.01*y + 0.0001*z)
Ordering in the 2nd direction.
Creating an inverse topology of the finite element mesh
There are from 0 to 42 connections in the inverse topology.
Set the node partitions by the dominating element partition.
There are from 78737 to 78847 nodes in the 4 partitions.
Succesfully made a partitioning with 480171 to 480172 elements.
Optimizing the partitioning at boundaries.
Ownership of 0 parents was changed at BCs
Creating a table showing all parenting partitions of nodes.
Nodes belong to 4 partitions in maximum
There are 14107 shared nodes which is 4.48 % of all nodes.
The initial owner was not any of the elements for 4 nodes
Checking for partitioning
Bad initial partitioning: 4 nodes do not belong anywhere!
The program encountered a major error...
Can't continue with broken partitioning
...now exiting to system...
What could be the problem?

Thanks!

OK, I found the solution on another post -- use "-removeunused" to the ElmerGrid command line.
Thanks!
