I am having trouble trying to mesh an airbox im playing with.
I have tried twice both times it meshes but flattens the geometry.
In order to create a mesh using automatic mesher, you need to merge all the solids and then extract from it the fluid domain you are interested in. Re-upload the geometry containing only the fluid domain and then start meshing. Hopefully this will solve the problem.
Thanks I will see if I can find a tutorial on how to do that in fusion 360
