TL;DR Summary

mcnpx ver 2.7 error

I have a problem. Previously mcnpx ver 2.7 was working on my computer. But now I get an error like this. ''bad problem in xact in routine tpefil chg_mem error''. Can anyone help? Am I making a mistake in the installation? Is there something I'm missing when making the ''PATH'' and ''DATAPATH''?.7

Hi @alperbugraarslan, welcome to PhysicsForums.

This is a memory allocation error. If you haven't run out of memory, it might be that something is causing the program to request far too much. This might be a corruption in a library or a mistake in the input file or requesting too many tasks.

I suggest making sure previous run files are out of the way, outp etc, all runt files, either deleted or in another directory and try running a simple input file.

I assume this is in Windows?
