The .inp can not run well

i want to run a simple .inp fluka file(the .inp file is written by vim compiler not flair), but the error occurs like this:

the file is uploaded,
Temp.inp (733 Bytes)

is there someone help me?

Dear @Newconcept_1979,

In your input there are two problematic bodies: “blkbody” and “void”. These are two spheres (SPH) and requires 4 numbers to be defined: the coordinates of the center and their radius. Instead, the input contains only 3 numbers and doesn’t provide a value for the radius.

@ amario, Thanks!
