Dear all

Recently, I have installed the openmx3.8 version. However, I can't find the executable file of NEGF, TransMain. Thus, transport calculation can't be acheived according manuscript. How to solve this problem.

Thank you

Dear Weiqi

The utility program TranMain is included in the main program openmx since version 3.8.

Please refer the following section of manual.
Step 3: The transmission, current (density, and eigenchannel)

Dear Mitsuaki Kawamura

Thank your for your reply. However, according to the example in test, carbon chain,

the negf-chain.tran0 0, negf-chain.current, and ’negf-chain.conductance can't be

generated in version 3.8.

In fact, in version3.7, I have calculated transport of some materials sucessfully.

Please give me some suggestion.

In our source directory, TRAN_Main_Analysis.o can be found, However, there isn't the part

Welcome to TRAN_Main_Analysis.
This is a post-processing code of OpenMX to analyze
transport properties such as electronic transmission,
current, eigen channel, and current distribution in
real space based on NEGF.
