[CIG-SEISMO] different results deriving from SPECFEM2D with two mesh-create-methods (Cubit and Gmsh)

[Hu Jiupeng]

Hi,
I got very different results for the same model，while the only differences
are the mesh-create-methods(one uses the software cubit and the other
gmsh).
I wonder which is more right or if I missed anything when I use the
SPECFEM2D program.
I checked the maximum skewness of both meshes but found noting abnormal.
Both maximum is under 0.75.
A picture of the model and a figure that shows the different results are
 in the annex.
Both Meshes and essential parameter files are also attached just in case
you may re-calculate these two example. By the way, the version I used
is SPECFEM2D-6.1.5.
Any replies will be great appreciated and sorry for the inconvenience.
