Hi,

I'm very greenboy in using cfMesh and I've tried create a mesh within my geometry in stl format. Firstly I've been intending just some plain mesh, only test one.

I used that very simple "meshDict" below as you can see, but it didn't work at all. And clearly I don't know why. The error message is in the attachement file. Thank you in advance for your help.

Hi Amadeus88,

thank you for your interest in cfMesh.
As far as I can see from this, you meshDict is completely OK. I have tried to run cfMesh with it, and it runs fine on my machine.
We have observed the error message you are receiving on couple ocassions when invalid characters were encountered in paths, patch names, etc. I see you have a non-english version of linux (I am guessing Ubuntu). Does your STL file have any patches (solids) with names that contain your language specific chars? Is there a possibility you share the STL file with me so I can replicate your problem?

Hi Tomislav,

thank so much, you were right. The problem is in stl file, but unfortunately I can't provide you the original stl file, because it's property of commercial company. When I've tried a other geomerty designed by mi own, it worked just fine. The issue is that the original geometry designed somebody else and I had the use of only igs file. I'm not aware of some specific symbol in the original stl file. Once more thank you.

Have a nice day

Hi Amadeus88

Just for future reference, whenever you see this "stripInvalid called for..." kind of error, this generally indicates that there are some unreadable characters in the file being parsed. This is (unfortunately) a limitation of OpenFOAM.

In case you wish to learn more about working with cfMesh, have you checked out the tutorials that are provided in the installer? they can be selected as an additional option during installation, and they show you how to use various kinds of refinements, as well as how to use MPI paralelisation.

Feel free to contact us if you run into any more problems.
