I have copied the .msh file converted from adventure on windows to the folder smartvalve in simplefoam

The smartvalve is a new case I created by right clicking on the case browser and by using create case command.

The mesh file is placed in the smartvalve case folder. I have not did any proceedings in system and constant directories. First I started the mshToFoam command directly.

The mshToFoam command exits as like this

Hi Hari!

a) you are not very specific: what was the msh-file generated with? etc
b) from your introduction I assume that the msh-file worked on windows? Propably the file was touched on the windows-system and introduced LF/CR instead of only LF and now the converter is choking on the CR. See and use dos2unix on the file

Thank you Mr.Bernhard, Sorr
Thank you Mr.Bernhard,

Sorry for the inconvenience.

I have created a mesh file from the IGES of a part by using ADVENTURE ON WINDOWS. I have saved it in .msh extension.

I rebooted to LINUX(OpenSUSE 10.3) and placed in directory as below

smartvalve is the new case directory i created.

When using mshToFoam command i used this mesh file cfd12.msh and the above said error occurs.

I am new to linux environment.

also with reference to your website where to execute the "tr" command

Would I need to convert the .msh file suit to unix system? If means how to do it.

Could you advice me where to use this dos2unix command as whether in MS command prompt or in UNIX Xterminal itself.

Hi! dos2unix is installed o

dos2unix is installed on most Linux-systems (usually from the package of the same name)

Usage is easy (as the man-page will tell you): dos2unix test.msh
