Hello, X-flow,

When I tried to decompose examples/testlid/testlid.msh into two parts, the output looks NOT correct . Do you get the same problem ?

If you use latest version from svn which is 1.4, you should use gmsh 2.5.
If you are using v 1.3, you should use gmsh > 2.0 and < 2.5.

Hi, X-flow,

I use the latest version which is 1.4 and try gmsh version 2.5 and 2.4. both get the same error.

It is a bug then. Can you try and correct it?

Yes, I'm trying to do it. it looks the problem comes from additional wrong old patches.

I tested with latest version from svn and latest gmsh and did not get that error.
Can you tell me exactly what you are doing? What steps?

  Hi, Zhicheng,
  
  Though it's 2019, I hope you can read this message.
  
  Do you still have the copy of the svn copy which solves your problem? The link in your reply is no longer available.

You can't load 2 files simultaneously. If you want to see whole mesh with partitions load testlid.ppp.msh
