Hi all,

I have found another thread for this topic but I did not find the answer or any help. Then I am reposting.

I have generated a mesh and I get the "ERROR #002100025"

| ERROR #002100025 has occurred in subroutine Chk_Splane.
| Message:
| The symmetry boundary condition requires that the boundary patch
| mesh faces form a plane or axis. However, face set 9 in the
| symmetry boundary patch
|
| SYM
|
| is not in a strict axis, which means that at least one of its
| faces is not parallel to the others. To make the solver run
| you can do one of the following:
|
| (1) Make sure that this symmetry boundary patch is in a plane or
| axis by checking and regenerating the mesh.
| (2) If the symmetry boundary patch is plane rather than an axis,
| change the tolerance of the degeneracy check by decreasing
| the value of the Solver Expert Parameter
| 'degeneracy check tolerance' (the default value is 1.e-4).
| (3) Increase the value of the Solver Expert Parameter
| 'vector parallel tolerance' (the default value is 1 deg.).
| Note that the accuracy of the symmetry condition may decrease
| as the tolerance is increased. This is because the tolerance
| is the number of degrees that a mesh face normal is allowed
| to deviate from the average normal for the entire face set.

Can you help me in any way? Do you have any idea about how to solve the problem?

Any clue to check if the hexa blocks go out from the surface? IF you contact me I can send you the mesh via email.

Thank you all,
Marco

This is usually caused by either:
1) You put elements from a few planes into a symmetry plane - the fix is to separate them into separate symmetry planes
2) You have a few elements in the wrong boundary face - the fix is to load it up in ICEM and check all boundary faces are correct
3) Your mesh is jumping across faces - this can happen in thin sections of mesh with ICEM, again the fix is to load the mesh in ICEM and have a close look.

How can I separate? I have a part called "SYM" that the professor gave me. Actually, in this part there are two planes one at z=0 and one at z=0.1 .

How do I separate two plane of 1 part in 2 parts?

In ICEM create a new part and manually move the elements into it.

Have a look at the ICEM tutorials for tips on how to do the basics like this.

I think that these are the problems I have:

If they are in the same symmetry boundary you will get the error message you report.

So you will need to sort those out into different boundaries, and it looks like there are some interfaces there too.
