this week in SimPEG
week of May 22
This week…
Thibaut has been working on adapting DCapps to visualize fields in challenging geological settings.
I have been continuing work on casing problems. In the figure below we compare methods for approximating a steel-cased well with a coarse-scale approximation for a DC resistivity experiment. One electrode is connected to the top of the casing, the return electrode is 2km away. Radial electric field data are taken along a line 90 degrees from the source-wire. Preserving the product of the cross-sectional area and the casing conductivity produces the lowest error when compared to the true casing model (baseline). The code is available on figshare.
Dom has completed the final stage of magnetic interpretation of the Kevitsa mag anomaly using SimPEG.PF. It may be the first time that magnetization direction obtained with an inversion is used as a marker for tectonic deformation.
In the meeting this week, we discussed the use of the Properties library for making SimPEG objects serializable and having validation on properties and classes.
In other news
- We got reviews back on the EM Paper, and to check and update figures, we reproduced results from a year ago — unit-testing for the win! The examples are up on the SimPEG docs and are available on figshare (1D inversions in frequency and time, casing sensitivity example).
See you next week.
