Refactor - driver for seismic wave propagation + faulting only.
Refactor - MPI communications for nodal quantities, driver.f90, depreciate PMLwhg.f90 and contm.f90, refactor qdct3.f90, rename qdct3 to ku, offFaultStationSCEC.

Full Changelog: v5.2.3...v5.3.0

v5.2.3

1. Python utilities are developed to setup and run EQdyna in the spirit of CESM2.
2. netCDF libraries are required for on-fault variables I/O.
3. Python post-processing utility is developed to visualize rupture dynamics. More to come and MATLAB post-processing scripts would be phased out.
4. Two compsets - tpv104 and tpv1053d - are working on Lonestar6 at TACC, UT.

Applications to high-frequency ground motion DRV1

Moderate changes:

• Add functionalities of
• 1. rough fault interface,
• 2. the effect of normal stress variations in the RSF,
• 3. output of ground motion velocities in binary,
• 4. develop post-processing scripts for ground motion data to get RSA map, etc.

Version: 5.2.2
Parent: 5.2.1
Author: Dunyu Liu (dliu@ig.utexas.edu)

Changes:

• Add Subroutine insert_rough_fault in library.f90;
• Add controlling parameter rough_fault (1 for having a rough fault while 0 for none); rough_fault is invoked three times in meshgen.f90.
• Add Subroutine output_gm in library_output.f90;
• Add Subroutine rate_state_normal_stress in fric.f90;
• Modify output_frt to include additional variables.
• Add Subroutine memory_estimate, which is called before meshgen, in library.f90.
• Uploaded to GitHub.com.
• Application: used in DRV1 that is presented at 2021 SCEC meeting.
