[snappyHexMesh] "word::stripInvalid() called for word" followed by weird characters
 

Hii,

Am trying to simulate the aerodynamics of truck in Openfoam,whenever am running the snappyhexMesh ,this error is coming

Overall mesh bounding box : (-20 -16 -3) (40 16 18)
Relative tolerance : 1e-07
Absolute matching distance : 7.116881e-06

word::stripInvalid() called for word ¿?O¹)^S$¸(<99>õÃ=Ã<9b>h¿^TÃ^H¾<99>õÃ=ëÃp¿ ó÷Ã%<99>õÃ=<94>i¿ÃNò½

Can anyone please tell me how to rectify this problem

Quick answer: My best guess is that your STL file is in binary format instead of ascii format.
