Negative Jacbian in "higher resolution" Marmousi EXAMPLE #1192

Closed AbolfazlKhanMo closed 1 year ago

AbolfazlKhanMo commented 1 year ago

Hello SPECFEM team,

I have a question regarding the "higher resolution" Marmousi model in the EXAMPLES directory.

When I use the files in that directory, I get this error:

32553 elements have a negative Jacobian, out of 148022 i.e., 21.9920006 %

It seems that almost 22% of the elements have negative jacobian! Can anybody help me with this? or potentially share the correct mesh files.

Thanks very much, Abolfazl

Thanks for the report. I have fixed it and uploaded the new mesh files. It will be in the devel branch shortly!
