Importing x,y,z coordinates via 'Mesh' to build a 3D geometry?

Hi people

I have x,y,z coordinates in .xls and .txt files, I converted them into .dat, at which I can import at 'Mesh' (maybe I was wrong?), but obviously I failed to see any outcomes upon clicking 'build all' or 'compute' at 'Study'. fyi, I did declare coordinate system at 'definition' and make sure that all coordinate names are the same as that in .dat files.

Kindly advise.

many thanks!

Hi

check/search the forum there are many threads about this. That is becausea "mesh" is no geometry in the sens of COMSOL. YOu apply the physics and BC's to a "element" such as a block, cube sphere ... then you mish this entity.

If you import a mesh you need first to reconstruct it into a higher order geometry Entity

Good luck
