SW4 (Seismic Waves, 4th order) implements substantial capabilities for 3-D seismic modeling, with a free surface condition on the top boundary, absorbing super-grid conditions on the far-field boundar...
Hi, I want to know why I get the following error: Warning: ignoring block line option ' unknown time function: GaussianInt using default RickerInt function. I used another time function...
This PR allows for an option to save memory usage of FWI through bypassing recording fields at boundaries before waves reach the boundaries or over a fraction of source precursor....
This starts the work to integrate SCR into the (synchronous) HDF checkpoint path. Since the HDF path writes a single shared file, one would need to run SCR in bypass...
In borehole seismic applications, one often has velocity information over certain depth interval only and one is generally not interested in surface phenomena. It would be advantageous to have a...
The `cout` stream needs to be flushed before calling `MPI_Abort`, otherwise the error message is not printed, at least in our case. (Invoking with `unbuffer sw4` is a workaround, but...
Hello everybody, I am using the 'randomize' command to introduce velocity perturbations into my model and would appreciate more literature on the statistical distribution of the random field generated. Is...
I found an odd discrepancy between the source code with the v2.01 tag and the release tarball made from that tag: the file **sw4/pytest/reference/meshrefine/refine-el-1.in** for the v2.01 tag is missing...
Hi It looks like the results for for VerysmoothBump source is not correct They are not correspond to declared Moment value (Mxx, Myy) because formulas do not have dimension -...
We have seen very large values in hvelmax images that are sparsely distributed in space, sometimes along lines. This problem only seems to happen after many time steps.
