[FLASH-USERS] [EXT] MPI error

[Reyes, Adam]

Currents from the Circuit drive used by Zpinch simulations will be in MA (see https://flash.rochester.edu/site/flashcode/user_support/flash4_ug_4p8/node126.html)

Everything else inside of FLASH, so variables that are evolved, or quantities on the mesh that get put into output files are in CGS. Electromagnetic units are modified a bit so that there are no factors of c or 4pi in Maxwell’s equations. This means that magnetic field is in units of gauss/sqrt(4pi) and similar things for other EM quantities. There is a nice table here: https://flash.rochester.edu/pipermail/flash-users/attachments/20121001/020d8ee4/attachment.pdf. Table 4 would show the relationship between FLASH & gaussian units.

For example, in the Z-pinch, I am a bit lost as to what the units of the current or energy outputs are. Thank you so much for your help.
