CFD analysis - problems when trying to genereate mesh

Hi,

I am trying to do a CFD for the urban environment for of a city district. However, I receive an error message when trying to generate the mesh.

Link to my project:

Do you know how to solve this?

Many thanks
Matti

Hi,

I hear from my teacher that if I created a new project, uploaded the model and then redid the whole process it would work. However, I have now receieved the following error message:

Do you know how to solve this?

Hey Matti,

First, I see the ‘outdated geometry’ message. Can you please re-upload your geometry and try the meshing again? There was a recent improvement on the platform that I think applies to this case, so it should allow you to advance your simulation.

I will also suggest you to use the Standard Mesh algorithm, with automatic boundary layer creation for easy of use. If later you need to tweak the y+ values, then you can try and use manual setup for the layers or the Hex-dominant mesh.

Hi,

my bad, I forgot to send the link to the new project, see bellow:

Can you see what the problem might be?

Thanks
Matti

Hi, I noticed that you followed the suggestions from the error message, and was able to create a mesh successfully by selecting a finer configuration.

In case this helps someone with similar issues.

Cheers

Hi, yes exactly, I changed to very fine and then it worked.
