<div dir="ltr">Thank you very much Felipe for the very fast and precise answer. <div><br></div><div>For the record: I have checked the "<span style="font-family:arial,sans-serif;font-size:13px">Overall domain bounding box" line after running the checkMesh application and I realized that the coordinates are of the order of thousands (thereby I have concluded that the channel height H is indeed considered as 1186.84 m). </span></div>

<div><br></div><div>You can scale the whole mesh using the utility <a href="http://openfoamwiki.net/index.php/TransformPoints" target="_blank">transformPoints</a> with the "-scale" option. (there a thread on this topic <a href="http://www.cfd-online.com/Forums/openfoam-meshing-open/72332-gmsh-units.html" target="_blank">here</a>)</div>
<div><br></div><div>I assume you should also be able to do this within Gmsh using the <b>Dilate</b> transformation.</div><div><br></div><div>Hope this helps.</div><div><br></div><div>Cheers,</div>

<div dir="ltr">Hi everybody,<div><br></div><div>the following might be a silly question, however I found it crucial for my modeling. </div><div><br></div><div>Background:</div><div>I have received a *.geo file which contains a channel whose height H is 1186.84 (in the CAD file this height H is measured in mm).<br>
</div><div><br></div><div>I will use OpenFOAM 2.1.1 in order to run my simulations, hence I will make use of the "gmshToFoam" application to convert the Gmsh file (*.msh) into an OpenFOAM mesh. In addition, I know that the natural units of OpenFoam are the MKS system (meter, kilogram, second), thus this leads to my question:<br>
</div><div><br></div><div><br></div><div>Question: </div><div>Once my OpenFOAM mesh is generated by "gmshToFoam", for OpenFoam the height H of the channel will be 1186.84 meters or 1186.84 mm?</div>
