icon4py-standalone-driver 0.2.0

ICON model driver.

model driver for Python ICON4Py

main.py contains a simple python program to run the experimental ICON python port.

Currently, it does only diffusion and solve_nonhydro (dry atmosphere with no physics). The configuration for the granules and driver is hardcoded in standalone_driver.py. Time step, total integration time, number of substeps, and etc. can be configured there.

The code is meant to be changed and enlarged as we port new parts of the model.

It runs single node.
