Create a 2D element connecting 2 nodes. This is useful when creating an arbitrary surface strain element in an area where mesh auto-generation has failed.

Create a triangular or rectangular element depending on the number of selected nodes. Directly input the node numbers that will become the corners of the 2D element, or select already created nodes in order on the screen. The element ID is automatically set to maximum previous number+1 and when entering the number directly, the number cannot overlap with an existing node number. Properties that will be assigned can be set or added and the mesh set can be created separately. Using the automatic generation function generates a mesh set immediately after node selection.
