free vertices, cubit

[marcus.stephan.schulze]

Hi,

There seems to be a problem meshing my cubit model, I had to create free vertices on the volume to apply a set of loadings from the roof beams, and Im guessing these free vertices not being connected to the volume is the reason for the error. Is there a way I can connect the vertices to the volume?

Kind Regards,

Marcus

I've attached the error image and the cubit file

Hey,

You have to been using your old laptop. All is ok with your model, it is not enough memory on it. I have a solution, but the result file is 29 MB, and have to find a way to send it to you. I have slow internet at the moment.

Regards,

Lukasz

Ok, you should shortly receive email, on your university account, with a link to zipped VTK file with the results.

Kind regards,

Lukasz

Thank you Lukasz,

Hi Lukasz,

How can I connect surfaces I created to the main volume so I can mesh it? Its not letting me mesh the volume as a result of the surfaces.

Kind Regards,

Marcus

You have to imprint surfaces on the volume mesh.

See fix:

imprint volume 4 3 1 

delete Body 3

delete Volume 4
