[Pw_forum] Running Environ with pw.x

[Oliviero Andreussi]

Dear Rolly Ng,

I am not sure about your question, are you concerned that no output specific of Environ is produced by your calculation? You say this because you confronted the output you have with the reference reported in the Environ/example/example01/references directory? 

You say that you attached the output, but I can only see the input files, from which I notice that you are running a calculation in which basically all the environment effects are turned off (environ_type = vacuum). Still, you should see some rather minor modifications in the output of pw due to Environ, in particular a summary of environ input parameters at the beginning (introduced by "Environ Module”) and a line at each SCF step saying  "add environment contribution to local potential” (while as a matter of fact no contribution is added if environ_type = vacuum, thus no contribution is reported in the following output). 

If you don’t see any of this things in your output, probably the compilation of QE + Environ had some problems or you are not using the right executable, since the input and the command seem ok and Environ 0.2 is fully compatible with QE 5.3.0. 

If you want to forward me the output or if you have other doubts or questions, don’t hesitate to ask the forum or to contact me directly. 

Best,

Oliviero Andreussi
