Can someone provide a manual? I forgot the specific meaning in the esh file, such as the specific meaning of the numbers in the picture
The highlighted line represents a polymer with six repeat unit of a random 1-to-1 mixture of ethyl and propyl monomers, capped with two methyl terminators, corresponding to an average of three ethyl and three propyl monomers per polymer. The m1:m2=x1:x2 format allows for defining average polymeric composition without being specific, which normally corresponds better to experimental practice. This in contrast to the definition
100 ethyl,3,propyl,3,methyl,2
where each polymer contains exactly three ethyl and three propyl monomers. A similar description can also be found in the EMC manual (see ${EMC_ROOT}/docs) under [4 Simulation Setup] => [File Formats] => [Chemistry File] => [Polymers], which should be at about page 48.
Thank you very much, when I run emc_linux_x86_64 build.emc My EMC is v9.4.4
