Dear fluka experts,

I compiled the input and mgdraw.f on my own laptop, it runs perfectly.  
Then I uploaded it to the lab server, the compiling process succeeded, after I tpyed the command, the .log shows as follow:

At line 519 of file cncprs.f  
Fortran runtime error: Bad value during floating point read  
Error termination. Backtrace:

The .log files are uploaded.[simu001.log](https://fluka-forum.web.cern.ch/uploads/short-url/sTXbrn1j6EOHvS4gnT2n3iubXlA.log) (9.8 KB) [simu001.out](https://fluka-forum.web.cern.ch/uploads/short-url/eLKlWSRtV9qVrAIHkZxedQX39PL.out) (42.9 KB)  
Note the fluka version with my laptop(3.0) and the lab server(2.X) is different, is there any chance to explain the problem? Could it be solved without temporarily upgrading the fluka version on lab server?  
Any suggestions are appreciated! Thanks in advance.

Honghu,  
Best regards

Dear Honghu,

The attached output file shows, that the FLUKA 2011.2x.8 is used on your lab server.

Currently we are only supporting **FLUKA 4-1.0** available at [https://fluka.cern/](https://fluka.cern/)  
Please install this version, and try again. If the issue persists, let us know.

Cheers,  
David
