Changing the tolerance cleared up the coincident nodes, not sure what the default tolerance is.
Merge "crackbeamf.msh";
Transfinite Curve {18, 19, 12, 13, 48, 54, 49, 55} = 17 Using Progression 1;
//+
Transfinite Curve {14, 15, 16, 11, 47, 51, 52, 50} = 3 Using Progression 1;
Geometry.Tolerance = 1e-5; // adjust value here for correct merge result
Coherence Mesh;

Re: Eigen value analysis
Hi,
Out of curiosity, how do you detect coincident nodes? By running Elmergrid with the merge command, or some other way?
Thanks, Rich.

Re: Eigen value analysis
This time running ElmerGrid with the merge command. Salome also has a merge command. In the past I have plotted the deformed structure and you can usually see the disjointed parts flying away.
Re: Eigen value analysis
Can I use this ElmerGrid command in windows? If so please tell me where to write this command..I use graphical interface of Elmer

Re: Eigen value analysis
You can use ElmerGrid in windows. You have to open a command window and type in the command. The path depends on where you the program but the command is ElmerGrid.exe if you do a search.
If you have the path set to elmer as described in
https://www.nic.funet.fi/pub/sci/physic ... dElmer.pdf
than you can open a command window, chang to your working directory
type
ElmerGrid
and it will list the options.

Hi,
In the referenced document, GetStartedElmer.pdf, Section 7.1, 'Open a Command Prompt Anywhere' may be helpful for you, as it is Windows specific.

Re: Eigen value analysis
Hi,
You can also run Elmergrid from within ElmerGUI, without using a command prompt.
Open ElmerGUI, load your .msh file using 'File -> Open'.
Then 'Mesh -> Configure', under 'Preferred generator' click the button for 'elmergrid'.
Look for the input box near the bottom labeled 'elmergrid' containing the String '-autoclean -relh 1.0'.
Add '-merge 1.e-5' to the above string, and click on 'Apply' to close the window.
To execute the elmergrid command, click on 'Mesh -> Remesh'
If you check 'Model -> Summary', before and after running 'Mesh -> Remesh', you will see the number of nodes decreases after the elmergrid remesh operation.
Give it a try and let us know what you find.
Thanks, Rich.
