Since last week, [GitHub is restricting access to their services based on
|
|
|
|
|
user nationality and residence](https://help.github.com/en/articles/github-and-trade-controls>) ([see
|
|
|
|
|
also](https://techcrunch.com/2019/07/29/github-ban-sanctioned-countries)).
|
|
|
|
|
Such restrictions are incompatible with scientific standards in
|
|
|
|
|
international research communities like seismology.

Code to calculate synthetic stress/strain/tilt/gravitational fields on a
|
|
|
|
|
layered viscoelastic halfspace.
|
|

|
|
|
|
|
|
|
The fomosto-psgrn-pscmp software package is used by researchers worldwide. As researchers, we are obligated to retain open
|
|
|
|
|
access to all. To achieve this, we are now migrating our code repositories
|
|
|
|
|
away from GitHub to a new safe home. The new home of the fomosto-psgrn-pscmp repository
|
|
|
|
|
is at [git.pyrocko.org](https://git.pyrocko.org/pyrocko/fomosto-psgrn-pscmp/), open now.
|
|
|
|
|
PSGRN and PSCMP have been written by Rongjiang Wang.
|
|
|
|
|
|
|
|
|
|
To ensure a smooth
|
|
|
|
|
transition, we will keep a read-only version of the fomosto-psgrn-pscmp repository
|
|
|
|
|
at GitHub until 2019-10-01, when it will be deleted.
|
|
|
|
|
Packaging has been done by Hannes Vasyura-Bathke.

# Installation
|
|
|
|
|
|
|
|
|
|
A Fortran77 compiler is required and the automake tools. These should be standard on Linux systems.
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
cd fomosto-psgrn-pscmp
|
|
|
|
|
# To run PSCMP with more receivers/source points
|
|
|
|
|
|
|
|
|
|
1. Choose larger values for `NPSMAX` and `NRECMAX` in `src/pscmp/pscglob.h`,
|
|
|
|
|
e.g.:
|
|
|
|
|
```
|
|
|
|
|
parameter(NPSMAX=100000)
|
|
|
|
|
parameter(NRECMAX=40000)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
2. Recompile with `-mcmodel=medium`:
|
|
|
|
|
```
|
|
|
|
|
./configure FFLAGS=-mcmodel=medium
|
|
|
|
|
make clean
|
|
|
|
|
make
|
|
|
|
|
sudo make install
|
|
|
|
|
```
|
|
|
|
|
autoreconf -i
|
|
|
|
|
|
|
|
|
|
make
|
|
