Which version are you using? It works fine with the recent devel branch. But I tried on Linux and WINDOWS. |

I am running 8.1.0 version and I am using the master branch. I just looked into the devel branch too but it said that it had issues on Mac. As an update, I am able to run this example. However, for the simulation which has my external tomography file but a different issue occurs. The tomography file appears to be successfully read (see screenshot below) but the last velocity is the only one used and the material is made homogenous. I was trying to test if I can use a tomography file for a non-plane wave simulation and it was giving me the same issue. I included my Par_file, SOURCE, and external tomography file used for the run in the attached zip file for context. |

How did you find, it is using the homogeneous model? Can you also upload all mesh files?

Yes here they are. I used the plot_model_from_gll_or_binary_file.py script to plot the vs, vp, and rho and they were all one number. mesh_0000.zip |

I see. Can you send MOR1_interfaces_outsideonly.dat file? |

Yes, here it is. I only defined the outer portions of the model space while troubleshooting. MOR1_interfaces_outsideonly.dat.zip |

I think it is correctly implemeting the tomographic model. Does your model resemble the one shown in the snapshot? |

I was having issue running the tomographic_ocean_model example. It give back an immediate backtrace error when I run it either serially or with multiple processors. I am using an Macbook with a M1 processor so my guess is that there is something wrong when first compiling Specfem but I am not sure. When I tried creating my own tomographic model and running a similar plane wave simulation, the tomo file was read successfully but returned the same backtrace error when running the internal mesher. Has anyone else had a similar issue using an external tomography file?
