blockMesh - no spellcheck at convertToMeters;

lupacexi · July 4, 2018, 06:54

Hello.

Today I've sadly discovered there is no spellcheck at function convertToMeters; in blockMeshDict dictionary file.

BlockMesh just read it anyway without any error or information.
ex. converToMeters 0.001; will be read by blockMesh and it wont be actually converted to 0.001 scale.

...otherwise convertToMeters 0.001; will be read too but it will convert to correct scale.

This is in my opinion an error which can give very very bad informations. And can make confusions especially with new users.

Cheers.

Can't reproduce with OpenFOAM-5.0.
Which version are you using? How does your blockMeshDict look like.

Hi lupacexi,

I think what happens is that since convertToMeters is an optional parameter, blockMesh looks for it in blockMeshDict and does not find it because of the typo, therefore takes the default value: 1.

OpenFOAM scans the file and only reads what it needs, you could define any variable with any value in the dictionary and will not affect the program.

Best,

Pablo
