Hi there,<\/p>\n

I am modelling the laser welding process using Moving Heat Flux module in Ansys Mechanical.<\/p>\n

I would like to see the maximum temperature of the welding surface. However, I found the max temperature changes significantly with the mesh element size, even though I have already extensively refined the mesh.<\/p>\n

My thoery is that the heat load was applied on the first layer of mesh elements, so smaller the mesh elements lead to higher temperature rise.<\/p>\n

May I ask if this is the case? Otherwise I couldn’t think of any other reason that the maximum temperature keeps changing with the element size.<\/p>\n

Please see my settings and mesh as below. Thank you a lot in advance and please let me know if there is anything unclear.<\/p>\n
