I am using SimPEG.Utils.download for gpgLabs. The download messages are distracting in notebooks, so I wanted to suppress them. The option is controlled by "verbose=false", but it does not stop writing "Downloading ... Saved to:.." message.
Can verbose=false swtich kill all the print output?

I was having problems reading in a single frame of a solution using solution.Solution and finally tracked it down to the fact that although the first parameter of Solution is named frame you cannot call it using this as a kwarg, e.g. the two commands below should load the same frame but the second silently does nothing:

>>> from clawpack.pyclaw.solution import Solution

>>> frameso

Currently, the listing contains the Courant and Fourier numbers for the momentum equation, and the combined Courant/Fourier criterion. It could be interesting to also have this combined Courant/Fourier criterion for transported scalars. This might be especially relevant for buoyant scalars.

At the moment transformations such as ACCKernelsTrans allow the user to disable the check for valid node types when calling apply(). However, there are further checks performed in the backend when code is generated which means that it is still not possible to generate code for such a case (without manually doing it in e.g. the transformation script). For consistency (and ease of use) we theref
