Hi
I am using foam extended version 3.1
When I try to run any command like blockMesh, snappyHexMesh it gives following error

--> FOAM Warning :
From function IOstream::compressionEnum(const word&)
in file db/IOstreams/IOstreams/IOstream.C at line 74
bad compression specifier 'off', using 'uncompressed'
Create mesh for time = 0

Plz Help
I am not getting which type of error is this
Thank You

Quick answer:

1. Edit the file "system/controlDict".
2. Find this line:
   

   writeCompression off;

3. Change it to this:
   

   writeCompression uncompressed;

FYI:

OpenFOAM 4.1 and 6 (etc.) use

writeCompression uncompressed;

The OpenFOAM versions like v1912 use

writeCompression off;
