Hi everyone,
i implement a user own element for 6 nodes triangle und use 3 gauss points for integration. To calculate the nodal stress, for every element i project the values on the 3 gauss points to the 3 vertexes of the triangle using least square fitting, and then set mean value of any two vertexes to the midnodes of the edge consisting these 2 vertexes. At last i use avereging nodes value. I want to ask if my idea is correct and 3 gauss points are enough for the above algorithm?
Best
