thanks for the reply. i have tried the model with coarser grain struture of 4mm hexahedral element and as shown in attached image. it is showing results. but when i increase heat input from 300 to 838, it is again showing convergence error. At heat input of 300, peak temp is reaching 960 C approx. At heat input of 838 peak temperature reaching is approx 3000 C (although it is 800 C greater than expected), for the same mesh arrangement. kindly help. (its been 4 months since i am working on this convergence issues). all the boundary conditions and the materials are same as in previous posts.
