This directory contains Reprint of the Schmeling 1985 paper on effective moduli of a partially molten rock, in which typos in the appendix are corrected directory "routines" which contains matlab routines to calculate effective moduli as a function of melt fraction the content of the directory "routins" packed in .rar format You may download the matlab routines to your own diractory and start the program by running the routine Moduli_GUI.m. This routine opens an interface which is more or less self-explaining. The routine Moduli_commandline.m does the similar thing, but on command line mode. Please send a short note to me (schmeling@geophysik.uni-frankfurt.de), so that we know that the package is used or tested elsewhere. In that case we can also inform you about updates and corrections. The code has been written by Jan Philipp Kruse (jp.kruse@gmail.com). The code is in a beta-stage, so please report all bugs or problems to Jan Philipp Kruse or H Schmeling (schmeling@geophysik.uni-frankfurt.de). We do not guarantee that everything is correct, but we think that we successfully reproduced the results published in the original paper. J.P. Kruse wrote the code based entirely on the original equations given there (with the corrections in the appendix). Jan 12, 2011 Harro Schmeling
