Axisymmetric calculations are unstable in versions of SPECFEM2D released in 2018. The problem did not exist in the December 2017 version. The instability occurs on the axisymmetric axis where it inter…

Add full viscoelastic kernels in 3D_Cartesian, undoing full attenuation (already done in 3D_GLOBE in July 2013, but not ported to 3D_Cartesian yet), i.e. implement the UNDO_ATTENUATION option of 3D_GL…

For very coarse (and therefore fast, >100s) meshes, I sometimes get solver crashes with "recursive I/O error" when compiling with ifort.
forrtl: severe(40): recursive I/O operation, unit 6, file unkn…

Hi,
I am wondering how the seismograms outputted at locations specified in STATIONS are generated:
Are they computed via some interpolation algorithms by mapping the values (e.g., displacements…

Hello, I have built a mesh with three materials, I am assigning the bottom two materials statically in my parameter file and would like to use a tomography file to assign material in the top layer. Th…

Recently, I try to set a new model to do the study. My vertical fault geometry is about 2\*2km patches. The total length of fault is 200km,and the depth is 30km. So I set the SX = 512, then set the Dx…

Add option to use radial basis functions for 2-D and 3-D interpolation. This will allow interpolation from any point cloud.
Compute length scale based on RMS distance to N nearest points?
Use user-sp…

I created the Vp sensitivity kernel using a simple model (setup attached), and with the forward receiver amplitudes used as the adjoint sources. The sensitivity kernel amplitudes are very high on the …
