hi, ask u'r question please...

or u can send me message

Dear Jules Lloyd Hammond

Thank's a lot for share link's, I sure check them, my problem is related to selection type of mesh.I made several mesh but did not get the correct result.

Dear Mr Yaser Ghanizadeh , In comsol My problem is selection type of mesh for study in micro scale, can you help?

Elmira Ghazanfari Jajin yes of course...exactly what is your problem?

Yaser Ghanizadeh Thank's I will sent file for you
