We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

What are the nodal averaging options for fringing results in LS-PrePost?

      In the “Fringe Range” settings of LS-PrePost, a user can select among five different schemes for performing nodal averaging before fringing a result. The available schemes are: 1) None, 2) Nodal, 3) MinMax, 4) NodalDifference, and 5) NodalFraction. Let’s assume that a node is attached to four shell elements and the scalar value result for the 1st, 2nd, 3rd and 4th shell element is 0.1, 0.2, 0.3, 0.4, respectively, then: 1) None: does not perform nodal averaging and fringes the actual scalar value of each element. 2) Nodal: fringes the average value from the four elements at the node, i.e. (0.1+0.2+0.3+0.4)/4. 3) MinMax: fringes the average of max and min value surrounding the node, i.e. 0.5*(0.1+0.4) = 0.25. 4) NodalDifference: fringes the difference between the max and min value surrounding node, i.e. 0.4-0.1=0.3. 5) NodalFraction: fringes the (max-min)/Nodal = (0.4-0.1)/((0.1+0.2+0.3+0.4)/4) = 0.3/0.25.
