One more question to the time discretization – is there a rule of thumb on how to set the time discretization?
I’ve tried to use several discretizations on a simple half-space model but the results are completely different. The test script is here home_honza_.config_spyder-py3_temp.pdf (57.0 KB)
prb.timeSteps = [(1e-8, 20), (1e-7, 20), (2e-7, 10), (1e-6, 10), (2e-6, 10), (1e-5, 10), (3e-5, 10), (1e-4, 10), (5e-4, 10), (1e-3, 10)]
gives the following
whereas uniform fine discretization
prb.timeSteps = [(1e-5, 1500)]
yields completely different image
a discretization used elswhere
prb.timeSteps = [(1e-3, 5), (1e-4, 5), (5e-5, 10), (5e-5, 5), (1e-4, 10), (5e-4, 10)]
leads to a different image again
Sorry for the dull question, but what I miss?
And one more thing – is it possible to specify the rx loop size somewhere? I want to model the ABEM WalkTEM data, which has concentric rx and tx loops.
